If the probe of the multimeter lead touches the resistor lead, either side, and the Phillips head, or the B + rail circuit trace, the resistor is soldered to, and the Phillips head screw at the same time, there will ... | |
| Biasing issue with Audio Research VT100 Mk II @edward78, Just a word of warning in case you are not aware... The DC voltage on each side of the resistor you use to set the bias 130mVDC is around 420VDC to the metal chassis of the amp. If you do not have any of these or something similar I... | |
| Biasing issue with Audio Research VT100 Mk II @edward78 said: my multimeter is new and is from KAIWEETS. Model number? . I’m still only able to get to 129m V but that is close enough. The trim pot is now maxed out on the left channel (before it was the right), so it seems that the prob... | |
| Biasing issue with Audio Research VT100 Mk II @edward78 said: That’s a good idea with swapping to see if the problem travels with tubes or stays (with the amp). Will give it a try, also raising the bias slowly. Power tubes only! The 6922 tubes are biased for the tube sockets (circuits), ... | |
| Replacing dead woofer on ProAc Tablette Sig 50 (NYC area)? I did a quick search on Google and came across this: a little proac info. Discussion in 'Hi-Fi and General Audio' started by Lt Cdr Data, Dec 28, 2003. Proac are a little mean on what they divulge, so I thought I would share a little of m... | |

| Shunyata Altaira Grounding Station ........has anybody purchased this new product ? Kingrex said: I dug around Shunyata site and did not find where Calin talks about grounding with a bar of copper and 16 awg wire. Can you point it out.

| Puritan PSM 156 connecting Puritan Grounding Products? My initial thoughts are the GroundMaster, coupled with the GoundMaster City (no inclination to attempt driving an 8ft copper rod through my garden soil). . I do not have any personal experience with Puritan PSM Grounding products. I do have ex... | |
| Dedicated power circuits Kingrex said; Interesting question. A little while back I had a project where I had to run 55 feet, 2 circuits in one pipe on the outside of a house. I spun the hot and neutral only on the 2 circuits and pulled the grounds loose in the pipe. I m... | |
