I changed my mind again and used on-board sinks by dropping the relays. Gerbers uploaded, just the wait now.

Well it works! Absolutely quiet too. With Sennheiser 650s there's more than enough volume so I don't need any gain.

I'm using it with one of Andrew's general 3 leg reg PCBs, so just a simple LM317 series reg to get me +12V. I wonder if a nice shunt reg might be beneficial here? Any suggestions/thoughts?

I'm wondering about a Jung/Didden superreg which seems highly regarded, but it uses D44H11 transistors which are out of stock at all the usual suspects and it will be a long time before they have any more. Bum.

I just built the super reg and I got the transistors on Ebay from a guy in the UK. They seem fine. The regulator works a treat.

Thanks for the feedback Tony. I've been working my way through the monster thread on DIYAudio for some light relief - like many monster threads there there's a lot of noise between the nuggets. But I've found alternative recommendations for a number of the more tricky parts so may well give it a go.

I've PM'ed you the Ebay suppliers I used for the hard to find transistors and the AD825s/

Thanks Tony
