Price reduced as I need cash !This is the amp than Dan "Doc. Bottlehead" Schmalle built for the Paul Stubblebine studio a few years ago. This amp is la creme de la creme. It was awesome when originally built for the 6c45pi tubes. But I can be snobbish at times so I asked Dan to convert it to 437A tubes. And that baby that grammy winner Paul Stubblebine used to do his mastering went up another notch. It's a fully shunt regulated one stage amp with WE 437a amps and Peerless TL404 autoformers, with different output impedances and three inputs. Dan also built for me a tape head preamp in matching veneer and I purchased and had serviced an NOS Ampex 300. These three pieces, together with my Sony mdr-r10s made the best headphone system in the world. No doubts! Unfortunately I have four kids and a tough job and I was only able to listen to it very occasionally. The little time I can devote to music can't be with headphones. It's an awesome preamp as well, but without a dedicated room I have to use my living room and with eight amps powering my horns the preamp has to sit on the back bookcase and she doesn't fit. So I decided to sell it along with the Sonys. It can beconfigured for balanced sources with a 600ohm input impedance or single ended ones with a 10K input impedance. As Dan said, all of their tricks are included along with very nice exotic parts. He cried when he sold it and I will too. But having it here is just a distraction. In his own words "that WE437A amp includes what we have learned in the past ten years. The amp came back to us and circuit was updated to our latest standards when we converted to 437As last year. So it has a particularly cool combination of our latest circuit tricks and some rather exotic and rare parts like the TL404s, dual mono MQ power transformers and filter chokes, Daven fine and coarse attenuators and custom Jupiter parafeed caps that I would not be able to source anymore". BTW, this is the amp that made famous the TL404 autoformers. I paid 7.5k before the conversion to 437As and before Dan added the latest developments. I'm selling it with three pairs of 437As (two matched by ear in the pre itself by Dan) the other purchased separately and still NOS. The 437As alone are probably worth north of 2.5k. If the buyer is in the US I'm pretty sure I can convince Dan to give the baby a certificate of good health before she goes to her new owner. I have a Pelican case that was purchased specifically for this amp so that it can travel safely. I can accept paypal or a transfer to my bank in the US. Please ask any questions and I'll be glad to answer them or discuss the amp in more depth. This amp was used by Doc B in his VSAC 2008 awseome system and then at different shows to demonstrate the Tape Project tapes.
