Feedback (The good kind ) !

“Pat,
Thanks for the great work on the Fisher 400cx2.  It has brought new definition to the Zu Definitions IV.  Following the power supply rebuild, ground scheme improvements, recapping with Super Caps, and flawless build of the Gold Point attenuator/power switch this is one of the finest vintage preamps I have ever heard.  I try to shy away from the audiophile adjectives because I have a hard time finding much meaning in them, but this baby is musical with explicit definition.  Midrange expression is phenomenal and nothing is lost at the extremes.  I would put it up against just about anything (within reason of course) and am confident it could hold its own, particularly the phono stage.  Great job, money well spent.
Ryan”

 

I really enjoy improving the performance of the classics

MC30 Rebuild Project Part 2

January 28, 2014

So far we have the new McIntosh Mc30 chassis re-chromed, the MC30 transformers and base plates painted with gloss black automotive paint and now we have the first of 2 stuffed circuit boards all ready for final installation.

I have used Teflon coated silver aircraft wire which is a much higher quality than the original. All the resistors are hand picked to be less than 1% of tolerance and in most cases they measure exactly as the schematic says they should.

The black cap’s you see on the board are Solen’s made in France.

A special audio experience “The Classic McIntosh C20”

March 11, 2012

Pictured a McIntosh C20 pre-amplifier. Note the full compliment of Telefunkin tubes all NOS test! It came in with an intermittent noise in both channels. A few caps later along with some proper contact cleaning and a bit of “Tubeology” work with selection/match of the Telefunkin’s and our proprietary tube socket and pin contact enhancing process (DNA) It’s sounding  stunning! In audiophile terms, “fast, transparent, detailed, deep and layered sound-stage, engaging”front of 20c mcintosh pre-amp
