Have you bought your back-up supply of tubes, yet?

[Skratch]

You have to pair them up with the 250,000 dollar speakers with the 8000 dollar speaker cables

For 20 watts per....

Sounds like a job for: K-HORNS!

 

[mr_rye89]

I’m surprised they get 20 watts from one 300b, or is that total power?

They somewhat describe how they get 20w from each 300B instead of the typical 7-8w

I have plenty of NOS 6GH8 american tubes for sale. Any brand preferences? To use them in place of the 7199 you may actually rewire the original driver board.

The have plug in adapters to use the 6GH8 in place of the 7199 tubes so you can use either tube

You got any RCAs? I can probably get away with “lesser” 6GH8s because the Dynaco probably doesn’t run them above their ratings like TV sets do.

The 6GH8 tubes work very well in a ST-70 using the plug in adapters, I personally think they sound better than the 7199 tubes

 

[mr_rye89]

Yeah and those adapters are dirt cheap, maybe I'll get some when I order new octal sockets. lol so much for "Stop using muh precious TV tubes in your stereo amp reeeeee!"

 

[Skratch]

I have used different upgrade driver boards which use readily available 12au7 and 12bh7 and other boards that use ef86 and 12bh7

 

[nakdoc]

I'll check for RCA brand....I should have plenty. Most 7199 tubes were RCA by the way.

 

[nakdoc]

The 6GH8A tubes I have new are GE and Sylvania. I have used RCAs among many others. If the RCA structure is what you want I can look at the other brands and see if I find a match

TUBES??? Yup, saw them in concert

Well right on time as predicted, new sanctions may make it difficult to get Russian tubes and caps for our projects. Back when I started the thread it was predicted that the invasion would start in mid-Feb. Delayed a few days so as not to interfere with the olympics because China wanted that spotlight. Now how far will it go? Too many troops to think it is just an eastern territory grab, he wants the whole enchilada but might slow at the river.

More in context of a music/audio site, he just wants to get the old band back together again, one country (or parts of bigger one) at a time.

 

[J!m]

Yeah, Russia is so tiny. He really needs that real estate.

 

[mr_rye89]

Oh sh!t muh tulammo…….
