Slowly finishing my PeeCeeBee.
Used Alfet laterals for exit and ksc5303 ksa1381 for VAS.
Also polymer capacitors for feedback and panasonic FR for the rest.
One wrong resistor in one channel got me puzzled for a couple of days, but finally found it!
Will use a capacitor multiplier that I had laying around, for power supply.
Thanks for a fine amp Shaan!

Done. I'm sorry for the discrepancy. Thanks for your patience.

Awesome, was thinking, why can’t someone start a cabinet GB...its pain in the **s to find one here in India...buying via DIY cart is like paying in Dollars...not worth that cost..n of course next to no choice
Hi Shaan,
Correct me if I'm wrong, you mentioned that the 2sk/J output transistors can only accommodate max DC voltage up to +/- 35V Vdc. Would the Exicon output transistors will work with +/-45 Vdc? If so, I would like to use that power supply since I have it laying around for a long time.

Hi Fredlock.
A single 2S pair can work at 45V as long as speaker impedance is 8ohm. Same goes for ECX pair. If speakers are 4ohm then its safe to use 35V maximum.

The recommended transformer rating is 25V-0-25V 150VA for one channel. Maximum allowable transformer rating 30-0-30 180VA for one channel.
