The first pic is the panel PCB with all the circuit bards you will need to make this beast of a Power Amp.
No2 is the control board.
No3 is the pair of Power Amp boards
No4 is a single Power Amp Board
No 5 is the Twin SSR and Dc Blocker filter board.

Other info will be posted on this site https://seca.freeforums.net/thread/2...1&scrollTo=662











Power Amp BOM



BOM for Control PCB



SSR and DC Blocker BOM




A brief spec..

At last got the new PCB,s and all working lovely.
I have 4 sets left to sell there is 4 PCB,s on a single 2oZ PTH plater.
Two Power Amps
One SSR and DC Blocker with filters
One control pcb, allows you to turn ON/OFF Change bias setting from A to A/B. select Phono or balance inputs.
Chassis are you choice but I will recommend some when I decide I like them.

Max O/P 75W/Ch 8R, 140W/4R, 265W/2R
Max recommend A class setting max of 30W it will get warm so chassis and heatsink important.

BOM being done now. with ref to FEC,RS,Anglia,and CPC sorry no Maplin
Min Transformes 2 off 300VA max transformer 4 at 1KVA ach.
Max current at 20V RMS and no fuses just a bit shy of 98Amps cont( need 4 + 1KVA tranys)

The cost mmm PCB are not cheap still working it out,.
Parts that will be your costing and haggling talents.
