Below is a story I posted in the VM Forum tonight. This happened this afternoon. I hope you all enjoy it. SteveD: Another VM conversion of a non believer I purchased Gold Lion KT 66's for my 2266C. I emailed the tech that has done my amp/guitar mods for 15 years and asked if I could drop my amp off to be rebiased this afternoon and he replied that if I could be there by 6:00, he would do it and I could leave with it. That worked for me, because I was going to be in town anyway and it is 100 miles round trip. By the way, I received a tip from the Marshall Forum about a killer price for a 2466 and I went there to buy the amp. After I payed for the new one, I had to rush to arrive at my tech's by 6:00. I had never actually seen anyone rebias an amp before. He printed out the info for these tubes and then went to work. He then checked the voltage of the transformer and commented that it was really high for a 50 watter. At any rate he then did his calculations and plugged in the probes (after several steps I won't bore everyone with) and biased the amp. After he finished, he commented "this is one of the perts of his job" and proceeded to plug in his guitar. I have to give you just a little background first. I had asked him his thoughts on the VM a few months ago and he said he had never played through one, but he knew a couple of people that didn't think they were so special. He knew I was looking for another Marshall, so he encouraged me to find a good used 800 Series Marshall instead. Back to the story. The amp was in low range and he took a second to observe all the EQ knobs. He adjusted the preamp volumn knobs, the master volumn and then the volumn on his guitar. This guy is a very accomplished guitarist by the way. He cranked out some riffs and leads, while I carefully payed attention to his face. He commented how good it sounded but that it was a little dark for a vintage Marshall sound, so I turned off the midboost and he started jamming agian, occaisionally tweeking the preamp volumns. He then went to high range and played and tweeked some more. Finally after about 20 minutes of switching between the ranges and EQ tweeking, he laid the guitar in his lap. This is his actual comment: "this may be the best amp I have ever heard. It sounds like a boutique amp". This from a guy that loves vintage Marshalls and has actually converted to VHT amps. By the way, I had left the cab of my amp at home and he was playing my amp through a 4 X 12 VHT cab. I'm not sure what speakers were in it. It was so much fun for me to watch his reaction. I had almost as much fun as he did. I am going to drop my new head off next Friday so he can retube and rebias and leave it with him for a short time to enjoy. He is a great guy that has helped me a lot in the 15 years I have known him. He will have his own very soon. lol.
