Is there a Degritter Mk 2 coming
Hi Degritter friends, In our previous newsletter we revealed a bit of information on our plans with the concept machine that was showcased in the Munich HIGH END show. Since then we have received inquiries as t... 
Changing electrolytics
I would try to find Cornell Doublier caps about the same diameter as the OEM Mallory’s. That will make fitment easier, using the same securing bands, etc. Should be higher temp rating than the Mallory’s and try to stay with 10% of the max capacit... 
Changing electrolytics
Cornell Dublier. That’s what was used by Jon Soderberg from Vintage Amp Repair on my 3.9e and 6e. Also should add IXYS rectifiers and updated Binding Posts.  
Disadvantages of buying old solid state.
I would not be worry too much with Pass Labs used gear. May have to (need to) replace the power supply caps and all terminals. Replacing the caps will necessitate proper biasing per the service manual. Caps should be done given the .5's age.  Sho... 
Threshold SA/1 monoblocks cap issues, perhaps?
Ask Nelson Pass at DIYAudio.  
Threshold Sa3.9e
You can connect via XLR but flip the switch on the back panel of the 3.9e to RCA. It will work (as if using the higher input impedance on the 3.9e). But I always thought it was not a good idea. I know others that have changed the internal resistor... 
Sonic frontiers
Only issue I had with a SFI preamp were the relays that were used.  They sometimes would get stuck.  Sound, though not tubey, was great.  
Threshold Sa3.9e
LOL, uploaded the e series manuals a long time ago. Glad to see they are still up in the DIYA site. Used a 3.9e for about 20 years back in the day. Doubt your Aleph pre will mate well with the 3.9e using XLRs given the pre’s high output impedance... 
Fozgometer V2
My understanding is that the Foz (V1 and V2) uses channel balance and channel separation/crosstalk to set azimuth, but does not take into account phase angle to set azimuth. The Foz assumes the best channel separation/crosstalk will be at the same... 
Linear Power Supply?
I also have a Condor/Roadrunner. To get it more precise, level the plinth and platter better, and lube the bearing. I usually get 0.04 on Analog Magik or 0.02 on WFGUI by doing so on my VPI. FWIW, the older Phoenix Eagle/Roadrunner used a LPS sim... 
Balls.....
If your ball and thrust plate are not showing any wear, I would leave well enough alone.  If your ball or thrust plate are showing wear, I would change BOTH the ball and the thrust plate.  It is a relatively easy DIY job.On a VPI, you'll need a pe... 
LYRA DELOS CARTRIDGE TOO BRIGHT, THIN AND SHRILL SOUNDING
Also, I am extremely hard on Cartridges due to having a few beers and getting clumsy with the tonearm. So I assume there is absolutely no way that your clumsiness with the tonearm could have rotated some Moving Coil armatures off their axis or ot... 
VPI Scout upgades?
Biggest bang for the buck when I had my VPI Scout:  (1) MC cartridge, (2) tube phono stage/step up transformer, (3) thicker Classic/Prime platter, (4) VPI periphery ring and HRX weight, (5) Phoenix Engineering Eagle/Road Runner (Now SOTA Condor), ... 
Brand new Technics SL-1210GR platter wobble ... disappointed!
" Direct drive turntables have the best wow and flutter specs in the industry. "Everyone says this (and maybe it is true as far as "published specs" go). But those specs typically are measured based on testing parameters that are not real world (e... 
My new to me Herron VTPH-2A - First impressions
Congrats.  You might also want to try your SUT into the Herron's MM tube stage (bypassing the Herron's FET stage).
