- You may reuse the original transistors or switch to new Motorola complementary pairs: MJL211193 (BR6522) and MJL211194 (BR6521)
New resistors used: 0.25ohm (0.15ohm) and 47ohm (22ohm) - Jak na to + styl
Does this modification add sound quality? What do you feel is different from the original project?
Hello.Please send the amplifier circuit.

Good video friend, I'd be interested to know if you've modified your Aurum Cantus, those are beautiful. Mine, I had a resistor across the ribbon tweeter I removed, and recapped with Mundorf Supreme EVO Oil with Supreme Silver Oil added as bypass on tweeter. I am considering some work on my 4B ST too.
I have upgraded all drivers on the Aurum Cantus with SEAS and Peerless, and redesigned the crossover to match.
@@neighorizon-4190 Ah man, that's great... 👍
@@neighorizon-4190 What did you think of the wire Aurum Cantus used, I kept it - "OCC", but somehow still find it suspect.
@@rickysnit2163 The wires used are very high quality.
@@neighorizon-4190 Thanks Friend, I kept mine, glad you think so!
Напишу своё мнение: 1) Оригинальные транзисторы - музыкальней! Купите оригинальные, и верните как было с завода. Подбор по HFE - обязателен. По моему опыту, очень хорошие замены: 70484200/70474200, MJ15024/25 без индекса "G", от ON-Semi. MJ21193/94 с индексом "G" - много хуже. 2)Нельзя менять транзисторы на другие, без подбора фазовой коррекции. По схеме 4В это С 22.
