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………

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.

McIntosh MC 2105 + C28 + MR74 = More McIntosh For Sale

Well as you might of guessed we like McIntosh gear actually we really really really like McIntosh gear (yes even if it doesn’t have tubes : – ), it’s one of the few audio products that has consistently produced excellent sounding and visually stunning components.

What we have here is a Mint Condition C28 Pre-Amp MR-74 Tuner and a MC2105 Power Amp all of them are in need of a good cleaning, with the exception of the MC-2105 which will need new glass because this one has the typical de-lamination / bubbling on the inside of the glass. Also a bit of trivia, the MC2105 was used on stage by Bob Weir one of the members of the Grateful Dead back in the late 70’s and early 80’s. How Cool Is That?

Check back soon to see them brought back to their original specs and appearance and if you are interested in purchasing them feel free to send us an offer.

McIntosh = MINT MC60’s For Sale!

We are in restoration process of a pair of MC60’s, that when complete will be as nice as the ones pictured or just a tad bit cleaner!. Be the one to reserve this pair for you, all it takes is a deposit to  reserve them. We estimate final completion by April 30, 2012.. the pictured pair you see is a set we completed just a while back.

I wanted to get you a picture that would be fully represetative of this pair now in process. The work will be all power supply caps replaced, power supply fully rebuilt, precision matched critical circuit resistors will be 1% low noise metal film types. The audio signal path capacitors will all be matched Mylar (orange dips), all small signal tubes NOS test as new Telefunkins or RCA for drivers. Rectifiers all NOS test 5u4 types. Output tubes matched new issue Tung-Sol 6550’s. This is a full rebuild not just a few parts thrown in. Once complete a rigorous 30 hour burn in QC process begins, all voltages will be referenced to original McIntosh specifications. Finally the sound?.. Fabulous McIntosh 100%

These will go soon, act now $ 4500.00 (the pair)

Thanks, the “Tubology Team”
