Hi,

I read the 6P3SE is a great sounding EL34 replacement. Some people are comparing them to a winged "C". I found a source that has them listed at $7.00/tube. has anyone here purchased from ussr-tubes.com ? I figured
I can get a full quad for the price of one winged "C".

6P3SE (6П3С-Е) is closer to 6L6 than to EL34. It was designed to replace 6P3S (6П3С, exact clone of 6L6) in communications equipment, where long life with relaxed specs was in demand. Russian tube most close to EL34 is called 6П27С. It is a ray tetrode though, while EL34 is pentode.

Thanks,

Can a Jolida 202a use a 6L6, EL34, or KT77 tubes ?
I'm a tube newbie. I thought if the amp can use a 6L6, then the possibility of biasing up a 63PSE in it's place was good.

I've purchased from rutubes but not ussrtubes.

So, can we surmise it's more like a 6CA7, then?

I ordered from partsconnexion only so no personal experience.

The 6P3S-E's should bias up fine in your amp. I use them in my Jolida 302b, triode strapped at around 40ma idle.

I bought my matched quad from Jim McShane. He tests them properly, unlike some other sellers.

I did a toner transfer PCB for Kegger based on the 6L6 tube family coined the KEG-EAR Amp. The econo version had the 6P3S at 360V 45ma and they sounded great in triode mode connected to 40 watt 6.6k Hammond iron. The tubes had a faint blue ion glow... They also did well at 400V but I did not run them long at this B+. They did remarkably well for output power listening level into 4ohm orion speakers~89db/w/m and min 3ohm.
I upp-ed the B+ to 525 and put in a set of svet-6550=c= biased at 50ma in triode mode and this was my favorite of the experiment, prefered over EL34 and KT88's.

These tubes are generally a couple of $ cheaper on ebay, which has the added benefit of their buyer protection scheme.
