Hi Andre,

Please forgive me if I have asked this question before, but how did your
Potato Amp come by its name?

Potato Amp is not the amp's name; it merely describes a single-tube
amp. Any single-tuber is a Potato Amp. It is a pun: tube-tuber-potato.
I don't know who first made the pun. I heard it first from Dan
Schmalle, known as Dr Bottlehead, of VALVE and Elecronic Tonalities of
Poulsbo WA, makers out excellent low-priced kit amps. It is a nice
consideration whether an amp built with two tubes in one envelope (per
channel) is still a potato amp. An example would be Dan's Single-Ended
Experimenter's or SEX; I had a sidebar in my original review for Glass
Audio of the SEX amp on the lexicography of potato amps but the editor
preferred to give the sidebar space to an advertisement...

Hi Andre,

Thanks for explaining the meaning of a "potato" amp so that it could
penetrate my occasionally thick skull.

I would consider "an amp built with two tubes in one envelope" to fit this
definition, in fact I am sort of fascinated by the idea of push pull
"potato" amp using a transformer for phase inversion. Do you know of any
suitable dual triodes, something roughly on the order of two 417s in a
single envelope?
