Thanks for this Paul. I too have heard good things about Chris.
Chris has worked on my amps a couple of times. He went over a twin reverb, and made it quiet and clean. Chris replaced the carbon comp resistors in a Victoria Victorilux, and got rid of the hiss. (I don't hear the mojo in olde schoole resistors, I want quiet!!!)Thanks for this Paul. I too have heard good things about Chris.
May I enquire as to what work did he do for you and on what amp? Does Chris have a website or could you PM his contact info? It would be good to have if I ever blow up an amp (heaven forbid).
Carbon composition resistors, while matching what OEM's were using back-in-the-day, have a reputation for getting noisy or hissy. I play quietly and clean, so any noise floor is too much for me. I want a quiet amp. After 10+ years, my Victoria, (built to back-in-the-day specs), was getting hissy. I had Chris Church replace the carbon comp resistors with carbon film resistors. I've got a MUCH quieter amp now. The same improvement in noise floor would have happened if the original carbon comp resistors were replaced with fresh carbon comp, but I would have had to replace them all again in another 10 years or so.Thanks Paul. Filed.
Question: in your opinion, the carbon composite resistors are quieter than the old school hobbies?
Being old, I worked in the industry from the days when carbon comps were replaced with films. They couldn't switch over fast enough! Not only do comps often make noise, they also tend to drift outrageously. When overloaded, they also can burst into flame! They were the only cost-effective type of resistor from the beginning years but their negative features were what drove research into better alternatives. Film resistors had almost completely taken over by the mid 1970's. I was working for TTI, a distributor of electronic parts in the late 1990's. We were the last distributor in the world for carbon comps. The manufacturer was Allen Bradley. Virtually the only market was for the military. They bought them because their specs were so flipping old that's all they could use! Updating mil specs takes longer than for a politician to deliver on a promise! By this time the military demand was just too small to be worth supporting, no matter what price we charged. We were selling 1/2 watt carbon comps for over $1 US EACH! Allen Bradley offered a final lifetime buy to their customers and then scrapped the production line.The problem with carbon comp resistors has more to do with manufacturers using barely rated or under rated ones in high voltage circuits. Most if not all the troublesome CC resistors in earlier Fenders for instance, were 1/2 watt. Bad idea as they were used as plate load resistors for the preamp tubes. The high voltage eventually takes it's toll on them. By the early '70's Fender decided to use 1 watt CC resistors there instead which solved the problem. These amps are far more reliable with respect to this problem.
Nice to be back, NR! Been incredibly busy for a couple of years. New lady and tons of home renovations. Giant trees in backyard blowing over in windstorms - seems every day there was something new!Nice to see you're back Bill....carry on.
