équivalent de VC5022

[orcad2010]

Good evening, I seek an equivalent circuit has VC5022 or scheme equivalent or method is to bypass circuit (for amp JVC A-X30)

thinks

Remove IC short circuit pins 1+2 , short circuit pin 9+5

Expect very low or no bias and you need to change resistor or trimmer on the VBE multiplier to achieve bias

Then you got your shelf a typical class AB amplifier ...no more Super class A

Kind regards

I can't even find a proper datasheet for this interesting chip.

Must say this type of JVC equipment was of really awesome build quality.

For the record I have 4 of these chips, removed from a working amp.

As per your request, equivalent schematic(s) attached...I guess the right one for your amp is the 1st one...good luck!

Hi .. I am looking for a VC5022 SIP, anyone tried the Chinese VC5022 part available online? I'm reluctant to order one as I have had bad experiences with Chinese parts in the past.

I would guess it is about 50/50 if you order from China. Not necessarily the most faked chip out there, but could still be bad or fake.

Anyway I have 4 used ones if you want.
