I'm quite partial to the metal tubes as well to mix things up a bit. I prefer the new/clean looking ones, but have to admit having a bit of rust on them gives the amp a "steam punk" look. Also have red and tall silver metal tubes.

I don't think we'll run out of cheap 6J5 tubes in any of our lifetimes. I also don't think we'll run out of 6SN7 either, but of course they tend to be a little more pricey.

There is no doubt in my mind that the high priced sellers are reading our posts - just watch the prices shoot up!

This lot is NOT $3 each - it goes for $195.00...

The 6C5G also have a cool looking mesh plate :)

I'll also be trying out another family member - the 76 tube - once my 76 to 6J5 adapters arrive. I think I have RCA, Raytheon and Fivre to try.

I also agree with this guy:

The Fivre 6C5G do sometimes appear on eBay for reasonable prices.

OK,so other than plate resistance the C5 and J5 are using the same pin-out,etc...?
Then on we go to the 76 and 37 mentioned in that thread you linked,yet you need an adapter for it?

Im aiming to move away from adapters entirely,except for in the rectifier slot. Me no like hum.

Looks like there is also 6L5. Haven't tried those yet, but just picked up a pair of NU 1940's black plate, foil getter. These tubes seem to cost betweet $8 - $15 each - which is ridiculous when you compare to the price of a similar 1940's black plate/foil getter 6SN7.

Edit: I was talking about the ST shape NU 6L5G.

If you have 6J5 slots, you'll need a 76 to 6J5 adapter. I guess I've been lucky with my adapters, as I've never experienced a humming with any of them. If you have 6J5 slots, then you can use 6P5, 6C5 and 6L5 directly.

I did notice that the 6L5G tube is a predecessor to the 6C4 which is roughly half a 12AU7.
