Very nice - where are the chokes?
Looks like you can see one to the back left of the power toroid in the first picture.

Great, thanks! These appear a bit less bulky than the ones I used. I'll post pics of my build when I finish it, hopefully next week. Also - where did you get those great heat sinks?
I've had those heat sinks for 25 years
Nice !
Anybody able to help?
I built the M2 using Teabags board but made an error on one and blew a few components. I put the optocoupler in the wrong way round and set fire to R12, R13 and R14. I have spare optocouplers and resistors but after replacing them R13 blew again.
What other components need checking and can I do this with basic equipment (I have a decent multimeter and a transistor checker from ebay)?

I said - right from the xformer ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
ref to schm in #1 , I would replace Q1 ,Q2,Q5,Q6,Q7,D1,D2,D3,R6,R7,R8,R9,R10,R11,R12,R13,R14,P1
now seriously - I would check them and find which part is kaput , but you must suffer , to drew reminder for future , to triple check before powering up![rolllaugh :rofl: :rofl:](https://files.diyaudio.com/forums/images/smilies/rolllaugh.gif)
besides that , I can't know precisely what else you done .....![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
