Gear for sale

My custom amps and preamps

From time to time I have new custom pieces for sale that are built ahead.  They are what they are and you can choose output capacitors, but that is about the only customization possible.  They can be wired for 240 VAC input if you are outside of N. America.  You never know what I will have so check back as this list changes monthly.  It is a chance for you to skip the build queue. Currently I have:

One final pair of the prototype 300b monoblocks.

$7999 US  SOLD, sorry.

I made a few of these and they are all sold.  This last pair was at Lynn Olson’s house and are being replaced by the final current production amps.  So these are up for sale.  Wonderful amps that are 300b push pull and about 24 watts each.  They are dead flat from 25 Hz to well over 30 KHz at full power, and at 2 watts or less they are flat down to about 18 Hz.  They feature both XLR and RCA inputs.  Input tube is 6SN7, with 6V6 drivers and 300b output tubes. They will easily drive 87 dB speakers and are very high current, but they are best mated to about 89 dB and above speakers.  These are improved over the version we showed at the Pacific Audio Fest in Seattle last summer.  Now they have interstage transformers in the first stage so there are no coupling caps anywhere in the amps.  Cathode bypass caps are all high quality film caps.  Comes with full tube set. I will finish updating them in the next couple of weeks and they will be ready to ship by the end of February.  First person to put down $1000 deposit will get them. If you are interested contact me.
