I'm so grateful for this list! There's no better resource for the type of
question that I'm about to ask. A few weeks ago, I
posted to this group because I had bought a re-issue, black Fender '63
Reverb from Musician's Friend and it arrived with a loose part inside. That,
in addition to footswitch problems prompted me to return it. I told
Musician's Friend to send me a brown one as a replacement and then had to
wait for them to issue a credit for the difference. So, I got the brown
Reverb yesterday. I expected the tube compliment to be 6V6 - 12AT7 - 12 AX7,
but when I took out the tubes this morning, I discovered that the reverb
unit has 6V6 - 12AT7 - 7025. The weird thing is that the 7025 is a NOS
Sylvania tube! At first, I thought that somebody had returned the unit this
way, but the tube chart inside the reverb unit indeed says: 6V6 - 12AT7 -
7025. Then, I looked at the schematics and it says that the tubes should be:
6V6 - 12AT7 - 12 AX7. Also, the Fender web site says: 6V6 - 12AT7 - 12 AX7.
Any ideas about why I got a NOS Sylvania 7025 and why the tube chart says
7025? I know that the original '63 reverbs had 7025. Do you think that I
should leave it alone? The pins on the NOS 12AT7 and NOS 12AX7 tubes that I
got are the same. Should I perhaps replace the NOS Sylvania 7025 with one of
these? Or, should I send this unit back? It's very confusing. If the tube
chart didn't list the 7025, I'd be convinced that someone else had replaced
the 12AX7 and sent the unit back. Do you think that Fender is making them
this way now? I guess it's not too hard to make a new tube chart yourself
and somebody could have done that before sending the unit back, but it seems
like a lot of work just to send a unit back. I'm just not sure why my unit
is set up this way. By the way, some of the other re-issue units that I've
seen have plastic handles, but mine is leather. Again, I wonder if Fender
has made these changes? It seems unusual that Fender would make a new unit
with a NOS Sylvania 7025, but I'm really ignorant about how these things are
done. Thanks for any help you can offer!
