NOS Telefunkens sound best, but are pricy. Try anything else to get your amp "on the air."
I like them, a lot. In terms of "pricey", I found four smooth plate that were Dynaco stamped, which costs much less than factory Telefunken stamped tubes. Got four for $380. No regrets for these great tubes.
As far as new, a similar sound signature as the Tele's, but more grainy and not as smooth, is the Gold Lion gold pin tubes. You can get them for about $40 per.
