| Turntable weight affects speed Assume: Without the added weight the TT platter RPM speed is correct when playing a record. Add the weight the platter RMP speed slows down when playing, listening, to a record. ("It noticeably slowed it down.") Remove the weight platter RPM spe... | |

| 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... |
