Many years of work have come to fruition. We debuted at THE Show Newport and just showed with Zu Audio at The CAS Show in San Francisco CA. The press is taking note we have a world class performer. The “Truth” amplifier  has lived up to all of our expectations and beyond. It is the “Ultimate” 2A3 tube amplifier

Marantz 7C Pre-amplifier MINT “Holy Grail”

You audio collectors and vintage classic Hi-Fi buffs and Audiophiles don’t need me to tell you much. You know what this is. Here we have a MINT, I mean MINT model 7C the king of tube pre-amps. This is all original, has the wood cabinet and all near NOS test Telefunkin 12AX7’s tubes no work has ever been performed on this, except possibly by Marantz, I see where the power supply diodes decades ago have been updated. I have run up on a variac and all capacitors are working fine and the unit functions all inputs working, its nice and quiet no hum, phono stage is working perfect, all switches and controls are noise free. I have supplied some pictures here as I opened it up. I will  ship , but due to extreme value I must have bank certified check and continental US sale and shipping only, If you make an offer it must be close to my asking price. I have not seen one this clean in 20 years at my shop.

It looks like it was in a time capsule, even the tube shield covers are bright finish still, LIKE NEW
This is the nicest one you will ever see

FORSALE – Pair of Heathkit W7-A – Super Rare & Super Mint

Each of these amps have had the following work completed by Classic Tube Audio.
You can own these for $995.00 + Shipping

  • New Power Supply Caps
  • New Bias Supply Caps
  • New Diodes in Power Supply and Bias Supply
  • All New Coupling Caps
  • New Thermistors for controlled slow start
  • Checked all of the critical resistors to make sure they are within Spec
  • New JJ El34 power tubes
  • NOS Used Tested 87% Matched 6an8 Driver Tubes

Chassis buffed and waxed and all pots cleaned with de-oxit

The only issue is one amp has a mismatched knob – I will include a matching knob so that both amps are exactly the same. –

Also one of the amps has a scratch by the plastic Heathkit logo maybe you can see it in the photos – or I can send you another photo of the scratch if you would like.

Overall this pair of Heathkits W7-A amps are about as mint as you can get all paint is shiny with a few minor scratches – (See photos).
The Cages are also very clean, however the cages do have a few scuffs and scratches.
see these on Ebay

MC30 Rebuild Project Part 3

Well, here we are – the 9pin sockets are installed into the chassis and the circuit board is also attached, now to figure out where all those wires need to go.

notice how the heater wires are attached to the 9pin sockets – very good idea I think that I may use that on one of my custom builds.

stay tuned for part 4

MC30 Rebuild Project Part 2

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.
