Bias adjustement pots.
appreciate for interesting article!less-likely the DC-component may be from the tube amps due to the damaged trim pot since they have an output transformer.on the other hand I can test the quiescent output directly before the transformer and see i... 
preamp vs. no-preamp
Anyone knows if there is a DIY guide or circuitry for transformer based passive preamp? 
Blowing Fuses in a Tube Amp
Keith...,I suspect that the problem is not in tubes.My friend has QuickSilver M60 mono amps that use EL34 chinese tubes. He did not replace them for more than 1.5 years and they still read to be in good shape. I already change tubes in my VTL MB10... 
preamp vs. no-preamp
Gboren the gain is the constant value on the most of the preamps. There are preamps with variable gain. Turning volume up or down you still working with already amplified signal.Changing the volume by changing the amp's gain is not efficient and w... 
Expensive vinyl rig - still not performing ;-
1.is your turntable PERFECTLY leveled?2.did you check if the armboard with platter on the one plane?3.is your platter rotates free?4.is your turntable coupled to the heavy and rigid stand? 
Blowing Fuses in a Tube Amp
there are lots of variables on that issue to check but this value is finite.1.the unstable bias supply can be due to the rectifying tube or ss diode or bridge; replace with higher quality rectifying diode(a-must) or ss-diode or the whole bridge.2.... 
Shure Stylus Gauge
i've just re-measured on my turntable(where i don't use any mat) and the reading are barely different that the difference cannot be captured by the Shure gauge meaning less than one tenth fraction of the gramm. 
Japan vs.the rest
i appologize for such offence before all japanese citizens and take that meant-to-be abbreviation back as no-way meant to offence citizens personally. 
Blowing Fuses in a Tube Amp
bias can be the main problem. what tubes your amp is using?i can tell you what tube pin you should check for grid voltage in order to have a correct bias before you place the new tubes there. also i can direct or perform an installation of the bia...

why CD why not analogue? 
Digitally remastered vinyl?
I own 70% of ECM released vinyl albums(arround 100) almost all digitally recorded or mixed and all with no exception sound superb. More than half on my collection are pressed in Germany. 
Can anyone help me on Audio Research PH 3SE?
I'm in the exactly the same situation and I use an Ortofon T1000 step-up transformer. You can do better if you get EAR one. A good step-up device is fare above $100. Otherwise you'll get too much of unwanted distortions and noise from your descent... 
Shure Stylus Gauge
the bearings might do ok but the pivoting position plays the vast role in this situation. the cartridge weight oght to be the same whether you place mat record or none of these. certainly the readings on the soft mat might not be pricese anywhay. 
Japan vs.the rest
It certainly depends on the brand and label inside Japan itself, but mostly yes, the jap CDs are more expencive due to their pressing and mastering quality. US CDs are not bad except the club ones from BMG and Columbia house. Lots of jap LPs laid ... 
Cassette deck head wear
I prefere to use no Dolby on my RX202 deck and I'll try to use Metal tapes on that. Mine records near-perfect on Type1 tapes and I believe that it will be perfect on Metal ones. Years back I used cheaper tape deck that were realy affected by Chrom...
