A tube being blown out?

Oh crap, who's going to take over as advisor =O

Nice tube dude!! It would be a toss up for me whether to put it in V1 or V2. The RCA has a great over-driven sound, the Amperex has more high and Mid frequencies. At times an Amperex can give you close to a Mullard sound, just more high strung. Not quite as creamy in the Mids. But try swapping the ...

Apparently I can't read. Its a Amperex Electrohome 12ax7 from 1964.

Usually there's a difference between 12ax7's and 12ax7a's. 12ax7a's being short-plates.

One is grey plate, one is short plate.

I did too, with V6 in the road king being the Phase Inverter.

On a related note...

I think I am up to 5 reported auctions for fake Tesla ECC803S, some of them are REALLY bad. Most are short plates, random writing...

Actually, the auction states that the Tesla e83cc is a "replica" of the much more expensive Telefunken ECC803S, which is actually true for REAL Tesla's, so it says nothing about the tubes he actually has. I have been looking on ebay. Its just hard to know if what I am looking at is real or fake =p I...

Ok.. According to some of the larger tube websites, there are lots of fake Teslas and JJ's rebranded with NOS Telsa labels. ( I was wondering if anyone could tell me if either one of these auctions is for a real NOS Telsa? http://cgi.ebay.com/E83CC-12AX7WA-original-Tesla-frame-grid-NOS-new-in-box_W0...

Does the change to Jan Phillips from Mesa have any effect on tone?

Do they just fit right into the normal EL34 spot? A

Hey,

I have a Road king II and I was wondering if there would be a tonal difference between Mesa's 5U4GB and Jan Phillips 5U4GB Rectifier Tubes?
