Further information:

I purchased the amplifier from a SNA member sometimes last year. I have kept the amp in a smoke-free, pet-free environment, take excellent care of it. It presents as new, is in perfect working condition. I am now selling as need more fund to purchase bigger amp for my speakers.

there are some quite reviews about the amp if you google it

The M88 integrated incorporates (4) KT88’s as the power tubes with a mixture of 3 12au7’s and a pair of 12AX7’s. Forty watts of pure musical bliss. It has 3 RCA inputs,( 1) XLR balanced Input plus a RCA PRE-In input in case you want to run it as a stand alone amplifier also.

To Bias the KT88’s is so simple. Just turn the bias meter to the appropriate tube (V1,V2,V3,or V4) adjust the bias current screw to the bold line on the meter, do this for each tube and your done. It is really a very simple procedure .It should take about 1 minute.
