Members Elias Graves Posted March 21, 2011 Author Members Posted March 21, 2011 Nope. 6F6. Got hold of some major old time toobz. The closest fit to what I uses is the 6F6. Looks just like a 6V6 but I haven't checked the base plate. Out of an old radio. EG
Members Elias Graves Posted March 21, 2011 Author Members Posted March 21, 2011 Also found a 6H6 and a 6C5 EG
Members sk8centilli Posted March 21, 2011 Members Posted March 21, 2011 Disclaimer: I'm purely ignorant in this area. Based on Wikipedia... maybe 6F6, KT63 Power Pentode. Octal base version of type 42. Moderate power output rating
Members Elias Graves Posted March 21, 2011 Author Members Posted March 21, 2011 6F6GT is what I have. All glass bottle. Same with the others. Looking around the net, it looks like it will work. If nothing else, I scored a couple of old tubes. The speakers may be useful, too. EG
Members GilmourD Posted March 21, 2011 Members Posted March 21, 2011 It... Might? http://www.duncanamps.com/tdsl/show.php?des=6v6http://www.duncanamps.com/tdsl/show.php?des=6f6 The pinouts are the same and the specs aren't crazy different. It really depends on the circuit, like most EL34 amps can also swap in 6CA7s, but you don't want to run old MusicMan amps that were designed around the higher plate voltage handling of the 6CA7s.
Members BoneNut Posted March 21, 2011 Members Posted March 21, 2011 Go ahead and try them. Just make sure your standing in a puddle of water when you plug them in. Old radios are cool man but seriously, watch out. You know what you need to get? A THD amp. You can plug almost anything into those suckers without a problem. The only issue is that they are so much fun to experiment with, you'll soon have at least three times what you spent on the amp, invested in pre amp and power tubes.
Members 23miles Posted March 22, 2011 Members Posted March 22, 2011 Good NOS 6V6's are plentiful and not all that expensive, why would you even want to bother trying this substitution?

Members Elias Graves Posted March 22, 2011 Author Members Posted March 22, 2011 Because I got hold of a couple of these tubes. Sounds like they will work but only plate voltages are low enough. Gets into a lot of stuff that's beyond me, so I'm not gonna do it. Don't really want to risk my amp for a maybe. EG
Members DaleH Posted March 22, 2011 Members Posted March 22, 2011 It... Might? Now that sounds reassuring.
Members GilmourD Posted March 22, 2011 Members Posted March 22, 2011 Now that sounds reassuring. Well, it came with the caveat that it really depends on the circuit in the particular amp. You don't wanna slam the tube with too much plate voltage and kill it.
Members Elias Graves Posted March 22, 2011 Author Members Posted March 22, 2011 So killing the tube is the worst that will happen? EG
Members Wyatt Posted March 22, 2011 Members Posted March 22, 2011 Depends on the amp. The 6F6GT draw more current than a 6V6GT, if your PT can't supply the extra current, you risk blowing it. So, I wouldn't run it in many vitnage/old 6V6GT amps. It looks like the 6F6GT can handle about 50VDC less plate voltage that the 6V6GT. So, I wouldn't use a 6F6GT in a Deluxe Reverb, or any other amp that is already pushing a 6V6GT really hard.

Members Elias Graves Posted March 22, 2011 Author Members Posted March 22, 2011 Thanks, Wyatt. The amp in question is a new Champion 600. EG
