I think I will. So, will any metal work? You said steel. Would aluminum work? I'll look for a sheet of something strong but not too hard to bend or cut.
Pretty easy thing to make either way. ![]() Is this cover meant for shielding, or just so you can't accidentally reach around and touch a live cap? I'm guessing it's plenty shielded being on the outside of the chassis. Last edited by JBennett; February 25th, 2012 at 08:40 PM. |

Okay... well I walked to home depot on my lunch break. Bought a pair of snips and a sheet of zinc. measured, clipped, and folded it (using my desk drawer at the office) in 10 minutes.
![]() ![]() Cost less than any available "doghouse" and I get to keep the snips! (and the zinc, which is supposed to be good for colds, right?) Thanks for the nudge MGD. |

So, I'm getting close to taking out the current guts. A few questions...
Seems to me that by looking at the schematic for the reissue and the original unit, the choke has two black wires. Does it matter which side the choke wires come from? Or is it not an issue which way it is fed from the rectifier board? Same question for the heaters. Are both green wires from the transformer interchangeable? Can I send either one to the tip of the pilot and then just send that wire to the 2/3-4/3-4 and the other to the 7/9/9 pins? Everything else is pretty clear, but the transformer wires are a bit confusing due to the duplicate colors. I'll be clearly marking the current connections with labels once I clip the plug ends and I'll send those to the same connections as on the RI. For example CP-8 from the PT goes to the AC switch and CP-3 goes to the fuse. (these are the two black wires from the PT) BUT!!!! CP-11 and CP-12 (the two RED wires from the PT) seem to be interchangeable?

Thanks Hackworth. I've gotten some more wiring done this morning. The power supply is all wired up to the fuse/light/switch/rectifier. Just waiting on a package from Watts with some jacks and wire and I'll be ready to wrap it up.

Thanks for watching. I hope to have it all finished by this time next week. (assuming my package gets here)
One thing I don't have that is on the originals is a brass plate under the pots... like in this photo of a vintage unit: ![]() Do I need one? If I need one, could I cut it out of the same zinc sheet I made my doghouse from? |

Package is still on its way. Cleaned up power supply wiring a bit and soldered in the two 100 ohm resistors on my octal socket. And soldered up the OT leads to the RCA out. And crimped a nut mount collar on my rectifier ground.
Outlet works, and the PT fires up a-okay. Jewel lamp glows, just above 130vdc before the diodes on the rectifier and just over 250vdc after they pass through the rectifier. 8ish vac on the greens. 130vac on the primaries. Something like that. Once it's all wired up I'll photograph all the readings. Jacks have resistors and are installed. ![]() ![]() ![]()
