Hi,
This is my problem, I hope someone can help me.
I bought a rect-o-verb combo a month ago, at first it sounded great but last week I notified a loose of punch, volume... since it is a second hand one I thought that probably I would have to change any valve, anyway I took the amp to a technician to make sure of the problem, he checked the valves through a kind of a tester specially designed to measure valves (mighty mite I think), and confirmed that one 12ax7 was bad, he also told me that the two 6l6 valves were not "compensated" (does it make sense to you?), well the thing is that he suggested me to put some used valves he had in his workshop that worked perfectly (also measured with the tester) and then save a good money. We tried but the amp does not sound like the first time... do you think that I have to put new valves or it should sound well if the used valves are measured and have right values with the tester? Also I would like to ask you about other thing I'm concerned about, is it normal that with the master to 5 o'clock (max) There's no changes in overall volume from output control at 9/10 o'clock on? I don't get more volume no matter how I increase the output control, it seems very strange to me... but actually I can't assure it worked different at first since I didn't need more volume. I have checked the amp with different cabins so I can dismiss speaker problems, tomorrow I will take the amp to the technician again, but I hope you can give me some clue of the problem, because the amp sounds awful!! it's not the loose of sound only, it has a very poor crunch as well...
