6H30 replacement

@stereo5 I checked with them.

Since I am stuck with 6H30s, I will have to look at different 6H30s than the Sovteks.

Give yourself a little time to adjust to the sound of the new amp. If you still don’t like it, sell it and get something you like. I don’t think different brands of 6h30s will make a big difference in the sound. conrad-johnson tried them once, they were called composite triode amps and preamps, and quickly changed back to their traditional tube types. If you have to take a small loss, that’s part of the learning process in audio.

questions like this should always be directed at the manufacturer... who would know exactly how the spec'd tube is being run, and thus what substitutes, if any, could be used

@astolfor … You are quite right in seeking a better quality 6h30 , I would encourage you to acquire some pre 1990 production Reflector Corp 6h30 DR 

they are relatively expensive compared to new production Sovtek and are becoming increasingly rare with a few unscrupulous individuals particularly on Ebay

listing Sovtek’s as NOS DR’s … Caveat emptor , however once obtained and inserted into your equipment you will realise how hard and sterile sounding the Sovteks are in comparison.

This guide should be of some assistance in discerning genuine Reflector DR’s

our good friend ficus lampizator has strong opinions on this. 6N6P - Not a western replacement, but a far easier to get and less costly (no spin) Russian one. 60‘s stock with the square getters are da bomb. I haven’t use them to replace 6H30’s personally and can not comment, but have used them in my own scratch builds and can vouch that they are great tubes judged on their own merits
