Ok guess the amp does power up .

Its using EKV550 as the power supply fets.

Wondering if the Z44's or 48's would work in this amp??

i found 1 defective fet.

Does it produce audio now?

Are these fully encapsulated?

yeah it produces clean audio now.

No the fets that are in it need sil pad behind them

The Z44s are the closest to the originals.
