That is Klimo monoblock amp. They were made in Germany in the 80’s and i believe early 90’s.

Great stuff

Do you have the other one ?

Chers

Looks like a project I did at DeVry in the late 60s. :)

Agree with @muljo. A pair currently listed:

Dr Klimo Kent Vintage Tube Power Amplifiers

Condition:

UsedUsed

Price:

US $2,699.00

Only pair I've seen in the U.S. for sale.  Several are listed in Italy and Germany.  I've read great reviews on the amps and they are quite a collectors item right now, especially the Monoblocks.

You are CORRECT!!! thank you very much. I appreciate everyone's help. I do have the pair & I intend to list them soon since I no longer have the space 

@jcbwgatos -- Every pair I've ever seen has a Gothic Script letter "K" label on the front left of the amp.  Is that missing from yours, I didn't see it in the picture.  If yours does not have it, I would suggest looking online to see if replacements are available.  I know in the past that has impacted the price quite a bit if it is missing.  Just my unsolicited 2 cents worth!
