Tube/Valve Amp Noise
"Trevor Wilson" wrote in message ... .. **Let me re-state the situation: * Peter Stein is supporting and servicing products he manufactured. I am servicing and supporting ME and other products. * There are others who service and support ME products. Due to the careful matching of semiconductors in all ME products, servicing the output stages by anyone other than PS (or his appointed successor/s) is a real bad idea. * Supplying schematics to anyone calling themselves a 'tech', in the case of ME, may be a very bad idea. Techs who are unable to perform even basic fault-finding, can end up doing far more damage to the amplifier. * In the case of most ME models, the output stages are modular in format. This makes removal and replacement a quick, simple exercise. Peter Stein (and his appointed successors) can effect service to those output modules and the modules posted back, safely, inexpensively and easily. Freighting amplifiers around the nation is not required. All that is required, is a competent tech. * I have seen many ME amplifiers which have been worked on by incompetent techs. The result is not pretty, nor cheap to rectify. * Poorly serviced ME amplifiers reflect badly on the product's reputation. Trevor Wilson One would have thought or at least hoped that electronics' would have advanced, improved, or at the very least progressed to a point where a 30 year old design could be called dated, superseded or at the very last 'outmoded' By modern technology, multi-layered chips, and modern manufacturing technique's At what point do you decide that up-dating, re-fitting, or simply replacing old components for new ones, is beyond the scope of transforming something into what you consider expectable or comparable to a modern day design. and at the very least on a par with what is available today. Or have you also updated your Holden commodore, by removing the starting handle out the front of the radiator, and while it might have been an advantage in the late fifties to have such a leg breaker, we now have modern electronics' making your starting handle obsolete. In short we get to the point where a 30 year old design, is simply that, nothing more nothing less, Of cause supporting something of that age does have considerable advantages, for one thing, nothing new needs to be learned, Old relics constantly breakdown, so an income can be assured in your retirement years. Of cause it could also be argued that a modern day design, would simply not make it in this modern age, and there would simply be no need to start manufacturing new models as the diminishing market and the production costs would make anything new completely out of reach, price wise to Jo Public, unless it was made in China, Korea or Taiwan, and for that to happen schematic's would need to be supplied to the factory of choice, with a undertaking that Chinese laws would need to change to protect the Copyright's of such valuable documents bassett |
