A few questions before I begin on the SSE

[Cifte12AU7]

Hi All!

First off, let me say that this forum is super helpful as it's chocked full of information and data.

I have a few questions that I was hoping folks could answer before I get cracking on the Tubelab SSE.

1. Choke. I am leaning toward using a choke. Is this choke sufficient or overkill? Fixed Hammond 193J 10H 200MA.

193J Hammond Manufacturing | Mouser

I do not plan on using the amp with very sensitive loudspeakers.

2. What gauge and type of wire do folks recommend using for spots where I will need to jump two points (e.g. solid state tube rectifier switch (SW1), as I'll be rectifying by tube only) or where I'm adding something in like a supplemental power supply capacitor?

3. What values/tolerances are ideal for the supplemental power supply capacitor?

For a Power Transformer, I'm using an Edcor XPWR059 (Primary (Input) Voltage: 120Vrms or 240Vrms, 50/60Hz.) For Output Transformers, I'm using Edcor CXSE25-5K (Secondary (Output) Impedance: 6 Ω).


Thank you in advance for any help you can provide!

That choke will be fine. 18 AWG will be fine for hook-up wire, make sure the voltage rating is adequate. UL AWM 1032 or UL AWM 1015 is a good spec for insulation.

This should work too:

But open frame, you can get a cover or opt to put it underneath the top (inside the chassis).

Thank you Zman01 and PDL!

Any recommendations on the specs of the supplemental power supply capacitor? I'm having trouble figuring out what to buy.

Here's a 100mdf motor run capacitor that has been recommended by others. I've used it in several tubelab projects

Thank you Colnago55!

Do you folks think this wire would suit me for hookup wire? https://www.remingtonindustries.com...wire-20-awg-ptfe-stranded-kit-25-length-each/

Sorry to be a pain. I just appreciate the experience everyone has of having done this and probably being more skilled than I am.

That wire will work well. That's nice little kit of hook-up wire.

No pain, please keep on asking we've all had help from the kind folks of the forum.

TEMCo sells direct.
AC Electric Motor Run Capacitor RC0096 - 100 uf (mfd) 440 VAC Round HVAC
Looks like a better price.

I buy enameled wire from them.
