I need to get new Tubes for my Altec 436C, they are making more high frequency noise the harder I push them. And it looks like cocaine resin on the inside. Anyhow I need 3 tubes: 6BC8 , 6GC7, 6AL5. Anyone know where I can find these new? Thanks!

www.triodeelectronics.com has at least 2 of the 3 tubes you need.
Hope this helps.

Plus the good thing about Triode is that they are here in Chicago at 5633 W. Irving Park Rd in the TV/Radio Lab building.

White shit inside the tube usually means the vacuum is bad -- not to be confused with shiny shit inside the tube, which is good.

If you're not up for the drive into the city to buy them from Triode, you can pay higher prices and order them from Antique Electronic Supply.

But if you don't mind the drive, Triode should get your money.

Thanks All!
I will check into both those places.

when i lived in DC, i bought stuff from triode and got it mailed to me. now that i'm back in chicago, i can actually go there in person. my point is, if you don't want to drive there, buy your tubes from them and have them shipped. the guys at triode are great folk.

Oh yeah... I'm spoiled by the fact that Triode is a couple of miles away -- I almost forgot they do mail order.

I ordered from Triode and it only will cost me $24 to re tube the old Altec. Is there anything I need to do before or during this process? Or do I just replace them and go?

I'm about to replace all 6 power tubes in my fender supertwinreverb and would also like to know what else i should be checking while i do this. I don't have a DMM yet or $200 worth of soldering tools, but i'll get there. For now it'dd be cool just to know the info anyway.
