Place the amp on its side and the rest is easy. Just make sure the amp has been off an unplugged for a few hours. The wire ... | |
| Audio Research VT 100 MK III vs. VS55 It sounds like the amp may be due for a re-tube. I try and tell people that no one ever sells a used amp with new tubes in it. If the amp sounds a bit diffuse,smeared, it might be time. | |
| Audio research vs audio valve I like the VS-115 and find it easy to service and well built. | |
| Audio Research VT100 MKII retubing blew resistors VT100 MKII's are a bit tricky to set up. They sometimes require 2 volt meters as trimming one trim pot will effect the others trim pot setting. I don't believe this should be done with output tubes in the unit. My guess is your shifting the DC ope... | |
| Audio Research Classic 60 & 120 owners Sebastianloke, where are you located??? | |
| 4 or 8 ohm with Harbeth On some ARC amps, the feedback is taken from the 4ohm tap. I find it sounds the best. When a speaker manufacturer says their speakers' impedance is 8 ohms understand that this is not a constant across the frequency response of the speaker. An 8 oh... | |
| When to get your amp up graded caps ??? Filter caps last between 10-15 years. Life span is a function of the quality of the cap,(some are better then others), the ambient temperature surrounding the cap,( high temps. will lessen cap life, and how long the caps are left idle. Generally s... | |
| Who has info on R&R caps in ARC D90B amp? I have on many occasions R&R'd those caps. If you are unfamiliar with twist-lock-lytic removal find an ARC repair facility near you to do it for you. You don't want to damage the through hole plating on the mother board. Some of those small tr... | |
| Audio Research SP8 MK II Sounds I am an authorized repair station for ARC and a past owner of an SP-6B. I have also owned a McIntosh C-20. They are very different sounding preamps. The C-20 uses a tube rectifier and so the bass can be a bit soft. The top end of the C-20 can also... | |
| audio research REF 150 Very well designed amp. Well behaved. Put out about 148W across 8 ohms. Single channel driven. | |
| No Audiophiles in Hollywood How about the credit for SOTA turntables at the end of House? I think I saw the turntable once or twice. | |
| Audio Research Classic 60 & 120 owners I suggest you find a qualified Audio Research Service provider. | |
| Audio Research Classic 60 & 120 owners Yes, the fans must be on in order to properly cool the tubes and the surrounding components. | |
| How to clean vol pot of ARC LS15 ...and those ARC units that do have actual mechanical volume controls use the Alps Blue pot and they are sealed. If the pot gets noisy, it would have to be replaced. Daniel, is the noise on one channel only, and at the same point every time you tu... | |
| Has anybody heard the new Audio Research LS 27? Granted, there are not thousands of ways to amplify a signal. Circuits change when designers have the insight to use a SOTA device in a new way. In tube design it would be utilizing a new tube. The circuit topology has to change to take advantage ... |
