I like what you have done. This is an investment. This is the way to do it. When they are this good if you need to tweak it again in 10 years it is worth it It should be reliable built so well and with adequate power transistor cooling. Are you running many watts in class A. 10 watts is really more than enough as at high volumes it is harder to distinguish fast ClassAB and ClassA. Fast Bipolars. My own amp is almost unliftable.
Does Avondale also supply Shilchar transformers, or is there another outlet of the Vodadara manufacture in the UK ?
No the R Cores came from a group buy on PFM
The Cap Smoothing boards are also from a group buy on PFM
Avondale supplied the bare circuit boards for the amplifiers and VBE

Thanks Boldname they sound fantastic and run really cool even when thrashed really loud, they are very stable and reliable and are 100W class A/B

My LM3886 chip amp, one of a pair that are both dual mono.

mbosko, what a superb build, congratulations. Did you make the PCB yourself or are they available from a supplier.

Thanks. The PCB's are from Chipamp Electronics. They do have a good quality look and feel about them. Next step is to spray the front and make a wooden cover. Case inspired by the the old A&R Arcam A60. Wiring style inspired by Naim.
My DIY project called TH-600, the fully balanced power amplifier.

Are the PCBs available for purchase? If yes, where and how much?
Thanks

Just an observation on above amplifier and the Krell Clone above, both seem incredible well implemented. There is one thing that strikes me as very odd, both place the output transistors on the very top of the heat sink, why not at the bottom ? which would yield a much more efficient use of the sink, heat does rise 🙂
