Subject: 12AV7 Tubes for sale

I have a couple of 12AV7s for sale. The 12AV7 can be used as a substitute
for the 12AX7. Many folks have recommended swapping the 12AX7 for a 12AU7
for lower gain for harp use. The 12AX7 has a gain factor of 100, the 12AU7
has a gain factor of 19, and the 12AV7 has a gain factor of 41. So the 12AV7
might be good to try as an alternative to the 12AU7.
