Hi.
Im looking for a quartet of 6550 to my Ampeg VL-1002.
It has a BIAS switch EL34 to 6550.
I dont like the sound of the EL34, so thats why im looking for the
replacement.
Which brand should i choose (for the money )?
I found JJ KT88 to have fairly good opinions on the net. Are these any good?

Thanks in advance for any help.

kisses.
