Anode Caps for 6P45C tubes, need advice

[Steve Morley]

I'm planning an amp using these tubes. Does anyone have experience with a source for decent insulated anode connecting caps?

Thanks, S.

The ones I got from GD-parts are fine. How many do you need? I have some left.

I think this is the size.

Thanks Koda. The Svetlana data sheet says they are 1/4" (6.4mm) caps. I've bought from GD before. I'll likely order 6.4mm and 7.4mm just to be sure, I only need two. I'll likely get some amp feet and other stuff at the same time.

Cheers, Steve

6.4 are the ones....Just get those.

I bought those caps from GD before (also upon Koda’s reco) and found them satisfactory. I don’t think the connector is phosphor-bronze, but it seems to grip well enough, and it is easy to retighten.

I’m always interested in Steve Morley’s audio adventures - what are you building this time? Sounds like a SE 6P45C amp.

Correct Francois.
I've always regretted not getting the HFN&RR kit of the EAR 859 back when Ken Kessler reviewed it in the November 1994 issue. The circuit was published in the review and I'll be implementing it almost verbatim. I'll be using Hammond OPTs, an Antek power trans and Russian teflon coupling caps. The pandemic subsiding here will allow me to get back into the tool and die shop that a friend owns in order torture some metal into a chassis.

Well, I think the bestest ever were these, as they, in connection with the brackets, allow to secure the tube from falling off it's holder.
Unfortunately I don't know where to source them. Mine are from dozens of TV sets that I scrapped in my youth.
Best regards!

Thanks for digging this up again. There are a whole pile of neat little-cap-ed tubes I would not mind building with. Type 3D21 comes to mind. A handful of sweeps too. Or have I mis-recalled the cap dia on the wee pulse tubes?

Silver plated, Beryllium/Cu fuse holders look good...if only RP stuff would take the heat...LOL
cheers,

…I don’t think the connector is phosphor-bronze…

Correction: I meant to say beryllium-copper, not phosphor-bronze.

Thanks, Steve, for the overview. Best wishes with your build of the EAR 859. Please report back on your progress from time to time.
