- Refreshed the F-2624 driver board after the protection light wouldn't come on. I am far from an electronics expert so I figured this video might help someone who's in the same boat as me.
I love the authentic burn mark on that service manual page😂
I realize it's been a long time but for anyone referring to this video you should replace ALL of the light blue/green pastel looking resistors. They are the so called fuseresistors and they will all eventually drift out of range. You can replace them with regular 1/4 or 1/2 watt (flameproof) resistors.
Also, there is an error on the PCB silkscreen - D07 and D08 are printed backwards - the stripe should be located downwards towards the edge of the board.
This is Great.I just bought a 8080 and the board is a little different than your DB.Just picked it up yesterday 8-16 2015.I have the same exact problem and cant afford to take it in somewhere If I could even find a place.You must have felt that great feeling you get when you heard the sound of the 8080 as she sprung to life.Im happy that u posted this.Thanks!
Charles Serafa Happy to help!
Thanks ,got it working just fine now.
Hello- Thanks for the video- I have a quick question- If you remove the 2634 board and power up, will the protector light will still be blinking red ? I have a 9090db that is missing the board that powers up and the protector lights blinks red even w/o the board. Thanks
You should do a LED light change video
Could you please tell what resistors are on the farthest to the outside.. the colors on them are faded on this board
Can you please post the parts list you purchased from Digikey. I am trying to do the same project and that would help greatly. Thanks
+Tim Hamby I used this one that was published on the AudioKarma site:
audiokarma.org/forums/index.php?attachments/f2624v2_bom_1-0-0-pdf.601251/
Thank you
you explain what the driver board does simply ?
How did you test your capacitors? Do you have an ESR meter?
Hi, I've got a faulty f.2426, I can't find the modern equivalent of TR9 & TR10(2sc984) can someone help me?
Also the power transistor (2sc1116 & 2a747) are very difficult to replace... Thank you so much!
Thank you.
How do you take the top
cover off?
Why R34 150 Ohm burning? I change twice and still burning.
Thx. for the confirmation. ;)
is the f2624 on 8080db the same as the 9090db anybody know.
Hi thank u I m To do it Sherie I buy staff
