I was reading through this thread and then I saw someone mentioned "head" amp. Back in the old days, this richard marsh did in fact have a head amp from decades ago. Then I was clearing through my stored items and I came across this "head" amp. I am now wondering if I could reuse the power supplies from this.

It is Dick Marsh's Pre Preamp with 4 improved Sulzer power supplies with pre regs by 317/337. This is from the 80s. I guess back then this was somewhat cutting edge. Something tells me that if the Sulzers can provide the current, then it could in fact improve the current headphone amp. Any thoughts? Richard. And BTW big thanks for your efforts on this and other projects.

Its good to see you have kept the good stuff even if you dont use MC cartridges anymore. The regulators will do wonderfully.... the regulators still get high marks for their performance and sound. You'll need one per channel as the Stock reg wont have enough current capacity to power both channels.
Nice looking workmanship. Mine never looked as good as yours and of others around the DIY site.

Unfortunately, all 10 boards have been sold by now!
I might do a rerun, since several people have shown their interest.
Again, send me PM.
