For your consideration: One pair (qty 2) of Heathkit AA-61 monoblock amplifiers. These are rated at 14 watts and use a pair 6BQ5/EL34 tubes running in ultralinear mode. A 6AN8 is used as input and phase splitter and the rectifier tube is 6CA4/EZ81.
Monoblocks are in good physical condition considering their age. Labeling on front panel is clean and legible. Some paint scratches on corner edges, but overall very nice paint finish.
Please carefully rev...iew photos for additional visual details.
Units were powered up with a Variac and were tested using a Heathkit preamp with a CD input. The level (volume) adjustment turns smoothly, with a hint of scratchiness but nothing excessive. I personally could not tell much difference when switching the damping switch between 'Unity' and 'Max', but the effect may depend on the type of music and speakers being used.
The transformers on each monoblock have the same manufacturer's marking:
Power Transformer:54-6310366140
Output Transformer:51-291386135
Overall this is a nice, clean pair of amps that do not appear on the market very often.
Note that no tubes are included in the sale and I have a handling charge to cover the cost of a new pack/ship materials and professional packaging.
