buying (NOS) tubes online

For around $50 (including shipping) for the stock set of four tubes just give them a try.

They have good feedback, so why not?

I buy from Brent Jesse as well.

Another vote for Andy Bowman. I have used him on a number of occasions over the years. He can be trusted and he will steer you in the right direction.

I bought matched set, hated their sound. he had me break them in for 60 hours (just on, no signal needed), then decide.

still didn't like them. I picked a different tube, 1/2 price of original pick. he let me return, gave me a refund for the cost difference, only cost me the extra shipping. 2nd pick sound terrific.
