Help with Single Power PPX3-6SN7 amp

I recently inherited this amp, which was shipped across the country to me. It came with 6 tubes. 3 were in plain white boxes marked 1, 2, 3 (which I assume was intended to correspond to the positions on the amps deck, front to back?).


1- Ken-Rad 6SN7GT  VT231

2 and 3 - Sylvania 6SN7GT  VT231


The other 3 are electro-harmonix 6SN7EH in original boxes "Made in Russia".

Are these all the same and placement doesnt matter, or if there is a difference am I correct that the order would have the Ken-Rad in the front?

Apologies if this isnt the correct forum!

Be careful


Research SinglePower on

Some people have had their SP amps catch fire. They are said to be very poorly built.

I would not have one in my home. But please do your own research . 

Just a friendly warning, I don't mean to rain on your (free) parade  :-)
