ARC vt100mkiii Questions?
I set it to 60 and the bass seems to get better.60? Not 65? If you do not have the owners manual you could call Leonard at ARC. He will tell you the proper setting.

Luna, First off I do not own a VT100 MK3. If the boards are new you will need to put some time on the components. Resistors, capacitors, ect. At least 100 hours with signal flowing I would think. Are the driver and power tubes new? If new they also will need some burn-in time. If the tubes are old you may want to have them tested. Power tubes maybe nearing the end of their life.... Also you stated the bias for the power tubes was set at 60 mVDC (0.060VDC)..... Is that what the owners manual recommends? Below is a link from AA and the discussion talks about the bias being set at 65 mVDC (0.065VDC). If ARC recommends 65 and you have it at 60 it will cause the amp to sound soft, not much punch...... Try readjusting the bias to 65 mVDC, you will not hurt the power tubes. http://www.audioasylum.com/cgi/vt.mpl?f=amp&m=86221 http://www.positive-feedback.com/Issue14/arcvt100.htm http://www.drhifi.net.au/Reviews/ARC%20VT100%20Mk.III%20Review/1.htm |
