Best place to buy tubes
I have a Audio Research VT-100 MKIII and it's time to take out the old tubes and put in the new. Were is the best place to buy the 6550's? I would rather not spend the money that Audio Research is asking, so I thought there must be some one how is testing there tubes at the same quality as AR.
Thanks
