You mean the ones that come with a Ceriatone? I have a set from Nik and they don't have any markings on them. Maybe Nik at Ceriatone can tell you where he gets them.

I am building a 100 watt non-HRM form a package 1 kit at the moment. I am using an old Schumacher twin reverb power transformer, a reissue twin choke, and a Heryboer Twin OT with 4, 8, and 16 ohm taps.

I had to adjust the PT cutout due to the shield on the Schumacher, but it was easy. I will likely have to adjust the dropping resistors to lower the plate voltages on the preamp tubes, since the PT appears to have been spec'd for 115 or 117 VAC, but again, that is easy.

The only downside is that Nik's relay power supply board is a voltage doubler that is designed for his transformer's extra 6 volt tap. I am using the typical radio shack 12VCT 450 mA transformer for the relays. I will either rewire the Ceriatone supply board or use the power supply board that came in the set that I ordered from Funkalicousgroove, back when he offered them for sale. Hope this helps.

Paul
