Legendary Air Tight ATM-1 EL34 tube amp, long term dealer demo with very low hours, excellent overall condition. This is the more desirable version with the large Tamura transformers and tube rectification. The sound is extraordinary! See the recent Art Dudley review of the newer version to get an idea of what this little amp can do. I thought I would keep this incredible amp forever but I recently got an Audio Tekne phono pre and now want the matching amp.

The amp looks excellent aside from one extremely small nick (0.7mm) as seen in the pictures. The plastic on the binding post nuts had cracked due to age. I contacted the manufacturer of those and they sent me a set of the 2019 replacement which is now gold plated copper to prevent oxidation. You can see a slight difference in color between the nut and the base plate.

Comes with the three factory signal tubes plus:

Matched quad of new production TAD EL34 (25 hrs)
Matched quad of new production Gold Lion KT77 (5 hrs)
Pair of new production Gold Lion GZ34 (0 hrs)
Pair of 1950's NOS Mullard GZ34 (200? hrs)
One 1950's NOS Mullard 12AX7 (50 hrs)
Pair of 1950's NOS Brimar CV4003/12AU7WA (50 hrs)
Three (out of a quad) Siemens RFT EL34 (200? hrs)

One of the Siemens RFT had went bad. I sent the remaining three to Ram Labs for measurement and to see if they had a single to match. They did not but the remaining three tubes tested excellent with no leaks. The measurements are now documented for future reference.

Will ship in the original box and then in a new outer box. Tubes will ship separately for safety.

$4500 - Shipping and PayPal not included.  Amp is listed elsewhere for lower price.
