| Sonic improvement with Threshold FET 9 refurb? I update a lot of fine audio gear. I don't see the controversy. The fact is, most electrolytic capacitors last 15-20 yrs, less if they're in a hot environment or the equipment had been sitting for many years without being used. Rubber gaskets on t... | |
| ARC owners do you have schematics As far as I know, ARC is no longer supplying proprietary circuit diagrams to customers. | |
| Anyone HEARD the qol 'signal completion' device? Less is more. Enough said. | |
| An affordable step up from AR SP14 is? As far as I know there really aren't any preamps in that price range with MC phono stages, especially if it's a low output moving coil you're wanting to use. I would suggest a high output moving coil and possibly a used ARC SP-16. When new, you co... | |
| help please Not a fan of the 20 year old plus Eagle amps and I have had the displeasure of working on them, even though they were designed by John Iverson whose past design work I admire greatly. I believe the circuit is a balanced bridge type. Not the most q... | |
| Cj Premier 11A fuse Those fuses are not cheap. Most C/J products use the large KTK fuse. I suggest you call them back and ask for Ed. Tell them you never received a return phone call. They should be able to help you. If the fuse is blowing your amp needs service. | |
| Audible Illusions hiss Minimal use is actually a bad thing for capacitors. Those units also have a regulated filament supply and its possible one of the transistors or the IC has gotten noisy. That would show up in both the phono stage and the high level stage but might... | |
| Need to replace meter lights with leds Carver amp I'm assuming the bulb you are try to replace is of the incandescent variety. First thing to determine is if the bulb is running on A.C. or D.C. If it's running on A.C. voltage, it becomes a bigger issue. L.E.D.'s want to run on D.C. not A.C. Next,... | |
| Power switch substitution for Marantz 2270 The ebay one worked fine. Already installed. The sub plate on this receiver has multiple holes for different switch screw width spacing....End cap installed with shims. | |
| Power switch substitution for Marantz 2270 Yes I'm doing that on Monday. I did rebuild the protection board with all new caps. This unit has FM Stereo issues, i.e. no stereo light. The bulbs are good. The FM bulb is also out and I'm wondering if that's the reason the Stereo light won't com... | |
| Jan GE 6cG7 what other tube recommendations The 6CG7 is also a 6FQ7 and you might find more options with that number. I've always liked the GE's or the Philips/Sylvania. | |
| Power switch substitution for Marantz 2270 I found a switch for 2270 on ebay that works very well and its a perfect fit. You may want to look for it there. It was $13.99 I believe, and just works. | |
| Upgrading coupling capacitors on EAR 834p Changing the value of the coupling caps can be critical and dependent on the locations of the coupling cap in the circuit. For example, doubling the value of the cap, in some applications, could destabilize very low frequencies and cause a rise in... | |
| Anyone HEARD the qol 'signal completion' device? My attitude, less is more. Another device in the chain complicates matters. | |
| Tube recommendation for Audio Research LS-2b? The Chinese 6DJ8 drew a bit more heater current then the standard Russian 6922 if my memory serves me. So a different value resistor was used for the Chinese tube. The Chinese tube was stock at the time that preamp was manufactured. |
