Amperex 7308 Goldpins Stereo Tube "VR5 #49"
Tested on a A Hickok 6000A Micromhos
NOS = 5500/5500
I'm no pro, but they are the conductance readings for the triodes. They should be higher than the min values for the tube to be any good. If they are higher than the NOS values they can be, but not necessarily, real NOS tubes. This particular tube seems to measure strong. Good measurements don't, however, guarantee that the tube is working and I've had my share of tubes that tests good but either doesn't work at all or only the other channel is working.
I'm also interested of the production code. Not sure why there is # instead of *. My PQ has a star which indicates New York. Finally if you look through the product pictures you can see that there is small crack of some sort above the PQ logo. This seems to be legit seller with 100% reviews and 30 day guarantee so I'm sure the seller will offer refund if you're not happy with the purchase. For this price I would also consider the driver grade from upscale.
Few links containing info about the tube measurements and such:
Don't worry about the A-frame. This tube in the link is real OG with globe visible (I would still check the production codes). My A-frames, for example, are newer and don't actually have any globe logo (therefore I call them orange prints). A-frame should be less susceptible to microphonics, but that's not really a problem with the audio equipment we are using.
