EL34 tubes to Proboi M50 amp - Click HERE for Original Thread
piipari
Hello,

I have two of these old russian tube amplifiers, Proboi M50. Other is working and other is in peaces. I would like to replace the original 6P3C-1 (which are getting rather old and soon will break) tubes with EL34 tubes, but since I'm pretty much noobie with tube-stuff, I don't have a clue how to do it. I haven't been able to find any information about my amp from the net. So, I'm wondering if anyone has one of these amps anymore and knows how to replace the tubes?

Hello!
Does your Priboi have the valves with connections on the top?

I think Gintaras in Lithuania has some. He's not on eBay at the moment, maybe he has a holiday, he's ID is "kwtubes".

You might also try in Estonia...

Cheers,
Tom

One cord from transformer goes to top of each tube. Rest of the pins is located at the bottom of the tubes.

That's a good point, that the amplifier is named Priboi, not Proboi, as the guy told me who gave me these amps :) Now, I started to find some intresting information about my amp. I think I found the number of the hifi-magazine where were an article telling how to change those tubes. Now I only need to find the thirteen-years-old magazine :)

Thanks.

Hello!
There's a guy in Sweden that has a web site for Pribois, too. And how to make them better, of course...don't know if it's up, though.
Good luck!
Tom
