I just saw this thread. Looks like a great project Joe! Keep us posted on how it’s coming along.
Thanks Dave, your help and advice has been invaluable to me! I'll be sure to update this thread, and I'm sure I'll have quite a few questions about implementation.
I've stocked up on some of the Jensen electrolytics that you recommended even if I end up going with the metallised Film in oil cans as it shouldn't be hard to make a switch. Also got the other parts you recomended like riken resistors and already had a lot of AN magnetic 2W but will prob go with the silver ones at some point. Also decided that I'll try the choke input Psu first as the guy who I spoke to was adamant that it sounded better for this amplifier after trying both ways.
Hearing the WE124 vs another WE Set amplifier (might have been a WE91) was an eye opener, I nearly decided on a WE124 but its quite complex and prob not suited for a first attempt.
