Tube advice
Tube advice
I need tube advice, what tubes can replace a 6L6 without being biased in a
guitar amplifier, and what is the sound difference?. Is there a good source
to find out this information?

Re: Tube advice
There are a number of tubes in the 6L6 "family", however, all are going to
require rebiasing. Truth be told, even if you replace your old 6L6 with
another, you still should check bias.

The result depends in information you have not supplied.

Hi,
The closest relative to the 6L6 is the KT66. It can be swapped in but
it's filament draws more current. Most amps will probably have no issue
with this, but it would be good to find out if your power transformer
can handle at least an extra .6 amp on it's 6.3 volt winding.
The EL34 will work as long as pins 1 and 8 are connected together on the
tube sockets. But again, the EL34 draws a LOT more filament current then
a 6L6. You can NOT substitute the 6V6. It is incapable of handling the
plate voltages of the 6L6 and also requires almost double the plate
impedance for it's output transformer.
Original KT66's from Europe have a slightly mellower sound then the
6L6. But old black and even gray plate RCA 6L6's also have a softer,
more laid back tone then todays modern production 6L6's or the classic
GE and Sylvania 6L6's of the 60's.
Personally, I would suggest trying the different 6L6's out there
today. Try Svetlana, Sovtek, and JJ 6L6's. They all sound different.
NOS vintage 6L6's are out there, but they are very expensive.
Modern KT66's would also be worth a try. Believe it or not, the Valve
Art KT66 has a very classic warm tone. I believe that one is actually
made in China. What type of amp do you have?

The EL34 requires more extensive socket modification and *must* be
rebiased.

Don't forget the 5881.
It is made now in Russia and is basically the same as 6L6GC.
Always check the bias when replacing tubes.
Anode dc current x Vdc from anode to cathode at idle should be less than
15 watts in guitar amps
with fixed bias.
