40W Glass A 300B tube schematic needed.

[GloBug]

Hey guys, I just got a really great deal on some tubes from eBay.

I bought them from SupercheapHiFifunMegawattaudioHotdog.

I only paid $350, much cheaper then other American 300B tubes.

Anyone have schematics?

Were do I find the sockets for them?

 

[Wavebourn]

Are they for 220V?

Russian government created the law that phases out manufacturing and usage of such bulbs, so they will be more and more expensive.

 

[GloBug]

Poor Anatoliy, you clearly missed the joke.

 

[rock4016]

Oh I think he got the joke. Also in the US such bulbs are going to become scarce.

I can't stand CF but the natural LED versions are pretty good, but expensive.

 

[GloBug]

Oh OK

Maybe it's time to start hoarding these bulbs.

That way in the future some of us can enjoy the natural warm tone that can only be attained by using vacuum bulbs.

Ace is the place with the helpful hardware man..

 

[GloBug]

OK, I just got off the phone with ACE.

Not only does he have the sockets, he is going to freeze some 14/2 and put it in the sun for an hour for me.

I've always wanted cryogenic cables already burned in.

He was very helpful.

Ask him for the cryogenically treated long grain 14/2 with rubber insulation and a pure virgin cotton overwrap, but make sure you warm it up in the sun before handling to prevent unfortunate appendage damage..

He has some, but his says it won't work for jazz.

I did however by a little heater to warm up the highs a bit.

Use Romex for jazz and easy listening. Heavy metal requires copper in conduit, and not just any copper........

 

[Wavebourn]

The best speaker cables for heavy metal are made of chain from a saw.

An externally hosted image should be here but it was not working when we last tested it.

 

[SGregory]

I prefer 00/3 aluminum. That way it can be easily hung from a wooden offset on floor joists. Use the third wire to bias the dielectric

Remember, those speaker cable stands must be pure Oregon Myrtlewood. Anything else is sonically inferior.

hey-Hey!!!,
And here I was, looking at the title thinking I'd get to read about a 3P PP300B design. I have seen a parafeed amp made with 25W, 240V lightbulbs as loads. Not bad at all in fact, for SE that is...
cheers,

Well there ya go.
