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………

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

Allied Knight-Kit km-15 mono amps X 2

I traded a 18 watt Marshall Clone amp for a pair of these super rare unbuilt Allied Knight-Kit KM-15 mono amps. The KM-15 is a small push pull amp. It has 2 inputs, a phono and tuner, and is rated at 12 watts RMS. The KM-15 uses a two 12ax7 tubes for the pre-amp and phase splitter, and 2 el84 (6bq5) tubes for the power amp section; and for rectification it uses a EZ81(6ca4) tube. See specs below.

As stated above these are un-built and came with everything as they did from the factory with the exception of the tubes. Someone went in and swapped out the original Mullard tubes and replaced them with some Sovtek (they are dated Jan, 1999 so they are even NOS at this point.

Now for the big question do I build them, or put them on Ebay? Part of me wants to build a vintage kit, I think it would be a hoot, on the other hand I have plenty of amps and have rebuilt several kit amps such as this pair of Heathkit w5m’s. – what should I do? Reply in the comments below.

And if you want to buy them and build them make me an offer.

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.
