Just got back my '71 Ampeg V2 Head from Stan Bailey - re-capped etc. WoW! Sounds fantastic, all the usual descriptors. Here is what he did: 1. Cleaned all of the potentiometers, jacks, and all contact switches. 2. Tightened and cleaned tube sockets and "holders". 3. Inspected filter, and bypass electrolytic capacitors. 4. Inspected for cold or bad solder joints. 5. Hooked up to dummy load, and check for output wattage, and abnormalities in the waveform. 6. Tested tubes for emissions, static current draw, and dynamic mutual conductance. 7. Check all components to assure they are in spec. 8. Inspected all reverb, tremolo, speaker, and footswitch cables. Fixed hum in reverb - (it is so quiet now!) 9. Biased output tubes. 10. Re-capped the amp. The caps were obtained from Antique electronics ($105.00). 11. Performed listeming test. He charged me a little less than 300.00 for everything - including parts! If you are in the area, have him do your work. Note - he did exactly what I listed here which is also what he lists at his website; if he does work for you, it may be for more or less what he did for my baby; the point is that in these hard economic times, here's a guy who does great work for an affordable price! Here's his website: http://www.mojotronix.com/ Just remembered - he did a bench test of a Master Volume device to see if it would fly and determined that certain cap-mods (changed values) would have to be done. This may explain why these amps with the MV didn't sound as good as the non-MV versions, if they kept the electrolytics stock in all V2's - more importantly, he did not charge me for this!
