Don't worry, I have successfully used these kapton discs in my Aleph5 clone. The pads are also fine for the AB100 .Does it matter using thermal paste vs. thermal pads?
Have a look at my test for heat sink mounting, if you like:using thermal paste vs. thermal pads?
David, I always try to put the transformers in the front of the amp, away from the boards, input and output.AB100 boards are done, except soldering in the output transistors, but I am going to wait until all the holes are drilled and tapped in the heatsink before doing that.

Transformers are Toroidy 250VA PRI 2x115v SEC 2x32v, with two separate mono cases, no soft start required, simple 15 amp switch, no speaker protection circuit. As basic and straight forward as possible. Going against the grain with no anti ringing snubbers based on my interpretation of Tom C's notes on his web site of their necessity.
Any thoughts on how you would lay this out?

Didn't show the front mounted on/off push button switch or the little ground loop break circuit board.
Thank you,
David.
Hi Could you please help with this info..Can the transistors KSA1381 & KSC3503 replaced with MJE350 & MJE340 respectively ??
You need to test stability by yourself.Hi Could you please help with this info..
Thank you sir..You need to test stability by yourself.
Do you have an oscilloscope?
Use one pair output only when first test.
Keep input signal low,use a bulb tester in series with the main voltage.
Mje are slow devices when ksa ksc are fast low capacitance drivers.
No Oscilloscope..shall test test it by working itself..You need to test stability by yourself.

... but just noticed that lovely PSU that you have as well
Can I purchase the Gerbers or point be in the right direction to purchase the bare PCB's if possible...
