Greetings. I read in one of the threads that the HTMCPS is recommended for HOMC - as compared to the HQMC phono section. Is the HTMCPS preferrable to the CNC? I have both the HQMC and CNC and love them both, but wonder if I should have the HTMCPS also.
Sorry for the dumb question, but what is the purpose of the B1 buffer between the CNC phono section and the preamp? Thanks for humoring my lack of knowledge.
All of the above are very good phonostages.HTMCPS is good for HOMC whereas HQMC is optimised for LOMC.

Pass B1 is used for impedance matching. I am using it since 2 years.It is one of the best,transparent and very clear.I am using it between CNC and DIY Power amp. I have recently built DCB1 on Omishra's designed PCB, and Its one step ahead than B1,smaller,cheaper and easy to build. You can see my build here http://audiokarma.org/forums/showthread.php?t=613244

Can you please take pic of wires away from trafo and little separate? Now I can see primary wires in pic.
I can read from label-
red-yellow are 0-115V primary one
Blue- brown are 0-115V primary two.
Yellow/green is screen
Please verify all 5 wires from above. If found true then proceed below.
Then join and seal (yellow + blue) together. Tape it securely and safely.
Supply 'L' to red, 'N' to brown.
'E' earth ground to yellow/green and chassis of metal near to transformer body.
Use grey black gray towards ops PCB.
Secure and tape other wires from shorting elsewhere. Remaining wires need not be used.
Use 10ohm 2W resistor paralleled with 0.1uF,250V joined between solder pad where black wire connected to PCB and chassis earth grounded point.

Hi GraingerI advise 100 Hr. break in for polypropylene capacitors.
Hi Grainger
They are Polystyrene. Are they any good? Tolerance is .1%
