Atma-Sphere in CO?

@cal3713
It sounds like these amps were used- any idea what version they are? The current version is Mk3.3 (older versions can be updated with full warranty reactivation).

@atmasphere I never found out from TMR. They had the 6sn7s in the 2x2 configuration, but had rounded edges on the power supply cover.  

Would love to hear a fully updated version at some point in the future, but only have funds for the units themselves at this point.

 @atmasphere I saw in listing by TMR advertised as mk3

If it had rounded corners on the power supply cover its a Mk3 at least.
Any idea of the condition of the tubes? The main reason we've found that people let go of our amps is that they don't realize how far downhill the tubes have gotten. The second reason is that they buy a new speaker to which the amp is not compatible. In your case, that is no worries as your speaker (or its predecessor) was designed with M-60s that Israel used to own.

@atmasphere Interesting. I do believe there is at least one bad tube in the amp. I had a channel go out and was able to flip which channel it was by switching out the tube complement. I got a new set of 4 output tubes from TMR and rectified the problem, but did not consider switching out all the tubes. I’ll see if they have a full extra set before returning...
