This thread is getting started to explore tube types, different numbers, that can be used in the Stereomour without any circuit modifications. That is, drop in equivalents.
These are the ones I have found. Variants like a 12AT7A will be in parentheses. I will modify the OP with others as posters contribute other numbers.
If anyone finds that I have a tube with the wrong pin out, or higher heater current than the Paramour can supply please post and I will modify the OP accordingly.
Paramour Tube Equivalents (in numerical order):
12AT7(A, WA, WC)
6060 (Brimar number)
6679
B739
CV4024
ECC81
ECC801(S)
6201
2A3
2A3C
2A3-40
I have also posted the instructions on changing the driver to a 76 tube. There was the original Paramour and the Paramour II which are slightly different. The 76 has less gain than the 12AT7 but in most of our systems that isn't a problem. One of the advantages is that it is the same tube shape as the 2A3 but a little shorter. It looks cool!
