Happy Holidays, Everybody!
Here are some photos of my work-in-progress BB Gilmore amp. As you can see, I'm using an external PSU that uses two discrete transformer/PSUs feeding 30Vdc each (unregulated) into the Gilmore PSU. I had originally bought the tranny units expecting to simply remove the trannies and feed them directly into the Gilmore PSU, but the units came already mounted with 30,000 mfd each of power filtering, fuses and independent power switches so I just kept the things whole.
I'll be upgrading the PSU soon with toroidal trannies and prob. Schottky rectifiers. It currently uses two standard silicon bridge rectifiers.
As for the amp section, the enclosure you see right now is an old computer case and I've drilled it full of holes trying to see which switch/jack connections work best. I'm also in the process of re-wiring all the internal wires with silver coated solid copper wires and teflon jackets. I had originally used Kimber Cable TC wires for everything, then cat5 and solid magnet wire and now I'll try the silver/copper/teflon combination.
Once I get everything down pat, I'll get a real enclosure and move everything over.
The controls/jacks from left to right are:
1) Passive/active (single ended/balanced) output selector. In passive mode, everything gets bypassed except the 50K DACT stepped attenuator.
2)Headphone/line out selector - left channel
3)1/4" Dual mono left channel headphone jack.
4)1/4" Dual mono right channel headphone jack.
5)Headphone/line out selector - right channel
6)Input selector (single ended only)
7)1/4" Standard headphone (not dual mono) jack
8)Stereo stepped attenuator volume knob.
9)Mini-phone standard headphone jack (not dual mono)
Any other Gilmore pics out there???
