| Scott 340A Repair help I may be able to help. Email me. | |
| ARC D-115 use half of tubes Same goes for the D115.... | |
| ARC D-115 use half of tubes Use all the tubes in your D70mk2. | |
| Tube dampeners on ARC gear ... FREE TWEAK Those dampers are suppose to be put in that position normally. They do not belong over the plate structure of the tube. | |
| Refurbish a Dynaco St70 And before Electronic Industries, Bill Johnson's company was known as Peplo. I don't know why or the significance of the name. | |
| Surge Protection for ARC Tube Amps I don't believe Audio Research recommends any power conditioners at this time. I might suggest you contact Kalvin in Customer Service at Audio Research and ask him directly. | |
| Quad ESL-63 and low-powered amps; Sun Audio, Atma Three watts is insufficient to drive the Quads. I do not know if an OTL amp would work with the Quads. | |
| New KT150 tubes? There are a quite a few ARC amps where the tubes will not clear the top cover. Be advised. | |
| winged c 6550c is not good for ref 5se?? The issue isn't with the Preamp, it's with the Winged C 6550. Don't use them! The last of those tubes that came from the factory before the plant burned down were awful tubes. Use a 6550WE. That is what ARC is using now. | |
| Audio Research M100 Thumping Yup I have an ARC SP-10 that's been modified and the work was simply awful. It's taken me forever to find all the problems wrong with it but I think I'm finally in the home stretch. | |
| Audio Research M100 Thumping Not really...Looking at it on a scope but it could also be a faulty filter cap as well. I would suggest having a tech you trust look at it. If that preamp has a tube rectifier in it, make sure the tube is functioning and if need be replace it. | |
| Audio Research M100 Thumping You may have a bad Hexfred in the power supply. | |
| Audio Research M100 Thumping The only other thing it may be is the coupling caps in the C/J are leaking DC voltage causing it to destabilize the M100's. It's also possible a regulated power supply in the C/J or caps in the C/J are defective. How old is your C/J preamp?? | |
| Audio Research M100 Thumping Run the amp without turning the C/J on, but leave it connected to the amp, and see if it motorboats. If after the 15-20 mins. the amp remains fine, it's not the amp. |
