EF86 Tube What to do with it?

[steviejr92]

I have this spare EF86 tube from when i made the Echo Foxtrot (which i just reminded myself i never made a build report for). Its been sitting collecting dust. I would like to know of any suggestions of how you would use it. Any cool circuits to breadboard with it?

Gonna need a few more parts but one of these should be a fun little project!

I second an AC-4! (here is mine for reference, and the schematic I went off of)

I’m driving so haven’t looked at the schematic in detail. Does this work off a single EF86 tube.

Yep, just a single EF86. Only 4 tubes total (you could drop 2 if you went without the tremolo and used a SS rectifier).

Ok I’ve bookmarked this. I’m going to take a look into this I’ve been wanting an amp and I was going to go the mojotone route with a kit but now I think I might go this direction!

Hi Dan,

Nice! Which power transformer did you use?

I'll have to double check, but I'm pretty sure I used the Hammond 269JX (I use Hammond on most all of my amp builds, and looking through my build notes, it looks like it was the 250-0-250 transformer). The OT was the P-T31 cheap OT.

Ceriatone "creme brulee" which is a take on matchless nighthawk AFAIK.
I dig that one.
