“A funny thing happened on my way to buy a McIntosh MC-240 stereo tube amplifier.  I knew exactly where I was going to purchase my vintage tube amplifier; Classic Tube Audio.  I have been working with Pat Hickman, Head Tubeologist, at Classic Tube Audio for more than a decade with Pat bringing my C-28 Preamp to factory perfection, he then worked on my MR-78 followed by my Thorens TD-125 turntable.  While looking at the 240 I noticed there was a pair of sorry looking McIntosh MC-30’s on the floor.  My very first McIntosh system included a pair of MC-30’s and I immediately remembered the warm beautiful sound the 30’s produced.  They were in pretty bad shape but I told Pat the story of my first really good stereo.  Pat volunteered that we could switch the project to the MC-30’s and I immediately jumped on the offer.  What a wonderful decision!  Pat brought this pair of sorry looking monoblock amps to perfection.  All visible areas were addressed; transformers were expertly brought to perfection including filling in any dents or dings with Bondo, sanded, primed and painted.  The transformers were top-offed with absolutely accurate decals, the epitome of attention to details.  What turned these MC-30’s into the beautiful amps are the addition of new chrome chasis with correct decals.  They just gleam in the their perfection. Every detail to match high quality capacitors, tubes, and all new components so that the closest matches were distributed between the two amps.  This makes a tremendous sonic equality between the amps.  To sum it all up the amps are visibly and electronically equal.  Like everything Pat does these amps were returned to perfection.  They look like brand new MC-30 monoblock amplifiers.  I do have a history of McIntosh amps that include my MC-2105 to the behemoth of all amps a MC-2300 that gives me a unique outlook on sound quality.
I worked in the Audio Industry initially as the owner of Quicksilver Audio repair shop in the House Of Music in Salt Lake City, Utah.  I quickly found that with my electronic technician education (ATN) in the U.S. Navy and ability to listen well I was a formidable audio salesman.  I quickly became a top salesman and later the Manager of The House Of Music.  The pinnacle of my audio career culminated in 3 day trip to McIntosh in Binghamton, NY.  Each day we were expertly guided on the many facets of McIntosh Laboratories by Gordon Gow.  We saw manufacturing, speaker research, marketing support, got to meet Frank McIntosh and every other facet of operations.  After the guided tour the evening was spent with Gordon Gow dining on Haute Cuisine followed by nightcaps back in the hotel.  The evening nightcap sessions were the liveliest and most informative sessions of the day.
The majority of my career was spent in the Personal Computer industry ranging from retail sales, software support finalizing in my 20+ year career at Central Washington University Computer Support Services.  My computer career only heightened my appreciation for vintage audio equipment with the introduction to digital music.  While opening many technologies digital advances always came at the expense of fidelity.  The pure sound of vinyl produced by tube technology became even more important in my quest for a really good sound system.
I’ve found that the value of power output has been become extremely corrupted with systems reporting output in the thousands of watts per channel.  One only has to sit down and listen to a whopping 4.2 watts of pure sonic perfection produced by the Whammerdyne “Truth” amplifier to understand fidelity wins every time over wattage.
I know that I have ingredients to build a sonically excellent system.  I owe so much of this to the wonderful advice and mentoring Pat Hickman has provided during our personal/professional friendship.  “Glowing Tubes All in a Row perfection”

Changes on the wind………………………….

Classic Tube Audio is growing!, now gong into our 44 th year, our shop work space is busting at the seams. You know what that means ?, cleaning up and reorganizing it’s just not working anymore. So with that said a new shop is in order and in the works over the next 60 days we are constructing our dream lab.

I will be sacrificing a lot of electronics in the process, I do not wish to move all this heavy electronics audio inventory. Below is a partial list. no sane offer refused. Yes sane, do not insult me or yourself by being a low-baller. I will tell you to go pound sand.. Ha Ha. But if you are fair with me I will be in kind to you.

As we move toward the build out of the shop I will post progress reports. With the new shop comes changes with me I will be spending a lot more time on the bench so I will be expanding my offerings service wise taking in more work. Turnaround times will improve, as to quality of work no changes we already are #1 top rated in the good old USA we live and breathe vacuum tube Hi-Fi, new old in-between………

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.

RARE !!!! McIntosh 50W-2 Amplifier RARE !!!!

Here up for sale just as we received it. This was in dry and unused storage for ?.. decades as far as I can tell. It was shipped to me in unknown operational condition. I have installed good test old stock tubes some original McIntosh branded and a new grounded power cord. I have slowly powered up on a variac. I found that I had some slight hum noise from the power supply and I have installed a temporary under chassis electrolytic cap to minimize the hum and get clean DC It’s near dead quiet now, the unit has now been run at full power and plays fine with no issues found. I would recommend that the power supply electrolytic’s be replaced if a person wishes to use this as a daily music amplifier.This unit is clean for its age. Some light scrapes and light dings, along with some paint wear as evident in the photos on the main amplifier chassis. This model was produced from 1951 – 1955 a total of 3068 units were produced. This units serial number is worn off by some past persons cleaning. The early McIntosh logos are clean and bright with very minor damage.It is sold as is, but functional. A McIntosh classic, this is the second model series that McIntosh ever produced.Price firm plus shipping $ 1500.00. (Original owners manual included) Just to mention how rare this is, This is only the third one I have seen in 31 years

McIntosh MC30 Rebuild – Chassis Shots

Well, 2 installments in 2 days – WOW a record, I just started to gather parts, and I just got confirmation from the parts distributor that my Caps are on the way along with some of the odd value resistors that I didn’t have in stock. I also ordered a few different types of high end tube sockets, I wanted to see which ones looked / fitted the best in the chassis. I will be posting some photos of those as soon as they arrive. in the meantime here are a few more photos.

Once I have figured out a price for the ultimate pair of MC30’s I will be posting it but in the meantime you are free to contact me with any questions or requests along with any offers for the completed pair.
