finally

Post by selloutrr »

:D I finally found a set of CTS 1 Meg Audio wire wrap potentiometers.
Most importantly the case and the wire wrap are correct. I'll swap out the shaft for a long shaft and the arm for the correct length or cut it to fit.

pot shaft

Looks like the shaft might be long enough. Also with these you have the option to solder on the back for the ground buss. 8)

That's the best part.
2 more parts and the period correct TW build begins.

I still need

(1) date code correct Mallory PVC601 .1uf @600v
(1) 100K 3Watt Resitor - a matching pair would be nice.
I have a dozen and all but one where way off spec.

I wouldn't mind finding an extra set of Switches , Pwr, Stby, Bright, and a Stackpole 80 4625 impedance selector (i'm not 100% sure the one I have is authentic).
I'd also be interested four 9K6 2W resistors in green, i believe mine are a deep grey.

I'm having a heck of a time getting a solid answer on what Power Transformer was used with the Grey Stancor A-3801 Output Iron. I haven't found a model in the Stancor catalog that matches the spec's of the pacific. The only model that is close to the correct voltage doesn't have enough mA to run the secondary or the heaters.
