12AX7 tubes for Music Reference RM-10
Both halves of the tube are used. One section is a grounded grid voltage gain section and the other is used as a concertina phase splitter.Sorry. I meant to say grounded cathode--not grounded grid.

Jim McShane can offer matched, low-noise tubes at a very attractive cost. 
VPI Aries versus VPI Classic
When the Classic came out, I called VPI and spoke to Sheila. I described my Aries (original series; HRX feet and SDS). She advised to stick with what I had. 
Conrad Johnson PV-12A - Remove Phono Board?
C-J does make a nearly identical stand alone phono unit called the EV-1, I believe. However, the coupling caps, at least the final output cap, is not polystyrene, and would have to be replaced to duplicate the performance of the PV-12 phono stage. 
Conrad Johnson PV-12A - Remove Phono Board?
To answer the specific question, it is very easy to remove the phono board if you choose to do so. The phono board is fully self-contained (with its own power supply regulators) and is held into place with screws fastening it to the main board. Th... 
What kind of oil to use for Oracle Delphi
Mobil 1 will work fine. 
audio research
I prefer the SP-8 over the SP-9. The SP-8 can be notably improved by replacing the Rel-Cap coupling capacitors and bypassing the opto-coupler in the mute control. 
Replacement for Nordost Cables in my system?
I honestly don't think the problem lies with your cables. 
Help needed - Quicksilver Full Function Preamp
I believe they are 2.0 MFD @ 450V Rel-Cap metallized polypropylene caps. 
Tube Preamp with adjustable gain
Used Music Reference RM-5. 
SS for Merlins VSMs?
Paul,I'd recommend you try and audition the new Quicksilver 88 monoblocks; I think they may be better than the V4s and you certainly don't need the power. They wouldn't throw much heat into your room in the summer either. 
SS for Merlins VSMs?
Paul,Tubes are Tubes and SS is SS. 
Power Tubes for ARC VT100 MkI. Genalex or SED?
The KT-120 is not a drop in for the 6550. In addition to the issues cited by Hifigeek1, the KT-120 specifies a maximum grid 1 resisitance of 50k, whereas many amps using 6550 tubes use a grid resistance of 100K. 
Berning EA-230 vs RM-10mkII with Merlin VSM
I have owned both the Berning (several years ago) and the RM-10 (currently), so I cannot make a simultaneous comparison on the same system. FWIW, I prefer the RM-10.
