Short videos to share with anyone who interest in what I do. There are three main parts. First, audio Hi-Fi stereo electronics designs including pre-amplifier and power amplifiers; phonostages, ac powerline filters and dc power supplies. Second part is about my Custom shoes and clothes artworks painting. The third part is about why and how I see the first two parts.
There are lot of "in progress" videos. Things like how I work day in and day out. Testing and production procedures. Explanation of my designs, etc.
In the custom artwork painting part includes a lot of things I have painted including shoes, clothes, furniture and speakers. The way I paint them and what I see from them.
The last part is basically how I see the world. My personal view point of things in general which often result to some very useful products.

A Quick Tour of my TOY House in June 2024.
My toy house, it just happens I sleep in one of the room. On the day of this video, it has total of 8 active systems in the house. I am currently working on the 9th and 10th.
In the video, we were trying to record the noise from the Onkyo A7 integrated amp. Which is one of the common problem of vintage equipment. Constants switch noise and other electrical noise. However, it didn't make noise when were doing the video. Here is the link to a video showing the Onkyo A7 vintage integrated amp making cracking noise from the right speaker.

Can i ask you something? If i have solar panels on my roof will i have less mains noise compared to having no solar panels??
@@GentielioGaming Not a simple yes and no answer. It depends on how the solar panels are connected and what they are feeding into. When I did my experimental preamp with solar panels, they were fed directly into the preamp power supply. No convert into ac and back to DC. In that case, it was dead quiet. Otherwise, they are so many ac noise in the system it doesn't get any benefit out of using solar panels at all.
@@angela-gilbert We do have a converter. Our house is only 2 years old and it came with solar panels. Then again i live not in a city, so i guess less noise.
@@GentielioGaming You will not get noise from the grid but the converter generates a lot of noise. Even when they claim pure sine wave, they are quite often more than 2%.

Dude, acrylic has excellent vibration absorbency. Maybe incorporate some in your designs.
The Willy Wonka of Hifi
as an engineer I can advice you minimize soldering to the PCBs only. and use connectors. there is shock proof connectors , water proof connector, explosion proof connector. industrial grade, marine grade, military grade. So don't judge connectors on the cheapest one on market. and you will save a lot of time and will be more secure joint than soldering.
Pinky....😂 Love it. Do it dot 🤗
what tube is that? Would you able to build something on the 6N3/5670 tube?
I can easily adapt any dual triode preamp tube to the circuit. May require slight rewiring for the tube pin out but the theory is the same. I am using more common tube because they are available. 5670 isn't a problem if you can supply the tube.
@@angela-gilbert also I see people selling those tube adaptor for switch to different tubes for different flavors, do those actually work?
@@MasterofPlay7 Yes, they do work in term of switch different between one type of tube to another. But be aware that different tube requires different bias. In most cases, it will work but may not be 100% of the way you want it to. It also requires different filament current. A lot of time when a tube filament current requires more than the original tube design, it will shorten the life of the filament.
@@angela-gilbert thank you for prompt response! What about the small input tubes? Those ones I don't believe they need bias, changing those would change the coloration
@@MasterofPlay7 Every tube needs bias. It is only the matter of manual bias or auto bias. Bias of a tube big or small is based on the current draw and the B+ supply. By plug and play without adjusting the bias, it may land on the different intended portion of the bias curve. It will works but would the sound suitable. That is the question. Therefore, by plug and play different tube into a circuit doesn't truly represent what that tube really sound like. There are so many things behind what the marketing department want to tell the public.
I think it could use a few more Farads.
@@2Blitzkrieg I am thinking adding another 20 Farads to make it to 2,500 Farads. Because keep saying twenty four hundred eighty Farads takes too much time. Short only allow for 1 min so I have to use my minute wisely.
@@angela-gilbert I think that is a perfect reason to add 20 more.
@@2Blitzkrieg I certainly agree. 😝🤪
Supercool👍
Nice 😊
Re: the unknown RCA turntable (record player) Found one with that cabinet on Kajiji, but it was sold a long time ago and the listing was gone. Wrong tonearm, though. Just looking at it's styling, I'd put it a bit earlier than what you believe. I'd say it's probably from the 1930's, judging from it's plain cabinetry and most definitely the tonearm style. By the 1940's, they were using the stamped metal tonearms. Also, it's JUST the record player, no radio or front speaker like so many others of it's era. This had to be either an add-on or something that the original purchaser had to decide on what they really wanted to hear due to budget constraints. Having looked through over a decade of RCA service manuals (1929-1942) over at worldradiohistory (forward slash archive-rca forward slash rca-service), it seems that this is probably an amalgam of old turntable parts placed in the RCA cabinet from probably the '20s or '30s, most likely what would have been a "farm" oriented unit - not flashy or ornate, but well constructed for little money. I cannot find that tonearm, Nothing in the RCA pdfs look like it. So, it still remains a mystery, but it is a cool piece of "ancient artifact".
Looks like the innards may be from a John Vassos designed Victor Special (designed for the 1939 World's Fair) transplanted into an older RCA phono box. ElmPhotography has some info on the Victor Special.
@@TheTrueVoiceOfReason Thanks for the info. It would be interesting to make it working again. All the cables are rotted. The tonearm cable probably need replacement too.
@angela-gilbert All that, and the idler wheel is probably as hard as a rock, too. I know you can buy them on-line.
@@TheTrueVoiceOfReason Nope. 😝😅 There isn't any wheel left. It has partially disintegrated many moons ago. It's a projects but I have other more pressing projects on the bench waiting at the moment.
Truly astonishing ! One question:you decide to play a record,what system do you use?
@@alexandervaneijken7741 It depends on the music type. There are 4 systems with turntable for now. They all have a different sound. It will depends on the music and how I like to hear them. Then decision may be made. 😉😆

I really appreciate that you brought up the affect dirty laundry has on the SQ of a room, I wouldn't of thought of that, also, that was the single most admirable toilet I've ever seen.
I was half joking about the dirty laundry. On the other half, when the laundry bag is really full and standing up straight, there is a slight effect on the bass in that corner. The toilet is directly on top of the septic tank. 😁
@@angela-gilbert Honestly, the American in me is mildly jealous of your toilet's freedom.
@@TerraBlacc1 You guys has LOT of free land in the rural area. If you live in a farm, you can do what I do. Not so much in the city. We have very similar restriction.
you must be pretty rich to own all those speakers
Took a long time to collect all of those speakers and amps. Although, same of them has been given to me for free. Friends who know I collect vintage audio equipment would gave their old toys to me instead of selling them.
@@angela-gilbert which one is your favorite or daily driver?
@@MasterofPlay7 I really don't have a favorite. They all sound different enough in different rooms to make them all fun to listen with different amps and preamps.
@@angela-gilbert but if you have to pick one which one would be?
@@MasterofPlay7 AAD7001 and CLS 2z. Can I pick two?
Great room with emphasis on GREAT.
Amazing! Thanks for sharing. Really enjoyed it! First thought that crossed my mind on the tour was “If Pee Wee Herman was an audiophile” 😆
Sometime I wonder am I still qualify to be an audiophile. I have stopped doing a lot of audiophile thing for a long time. Many of those I have never start. Because they didn't make a lot of sense to me.
Rainy today so after video i spent all afternoon plugging and unplugging my audio gear to see what was the weak link.Conclusion of my test : All my amps with small transformer have little to NO bass ! And very small sounstage compared to my bigger amps.Although small amps seem to be more transparent my big amps are just fuller and more musical! So all the smallies are back in their box , for now !
@@VirusForPrez Small amps need a special kind of speaker to sound together. Matching is the key.
How important are loudspeakers for you?...i see a wide variety of speakers,from very nice monitors to very simple floorstands and everyting in between. Do you have a favorite brand of drivers, type of built (br, tl or closed systems etc) i see some high sensitivity types of speakers like the JBL's ,but als alot of vintage speakers like those Kenwoods.....i did built my speakers myself and i am a fan of Seas drivers for their ease of sound and powerhandling.
@@SuperScalemaster I want to keep a variety of speakers around for testing amps. From audiophile speakers to very diet cheap road kill junk. Literally junk my friend picked up for me when ever you see them. They give me a wide range of prospective of how my designs sound on different type of speakers. In addition, I also take my designs to various location foe beta testing.

That is absolutely incredible the work and time you put into this. Would film bypass caps on the electrolytics do anything? On certain ones? I’d think they’d change the sound, but not necessarily for the better, but different.
