I'll throw in my two cents on this...

I just finished a TA-300 30W mono amp, and am not especially happy, or
unhappy.  Mark V is not like a Heathkit- I would recommend knowing something
about electronic design before tackling one.  Now, this is not bad because
their prices are very good IF you DO know something about design.

The TA-300 kit I got had an etch error on the pc board, and they were running
a filter cap rated for 50V at 50.3V.  That's a no-no- one needs to derate
for good, reliable operation.

Their designs are not first-rate, but are acceptable if you don't have
"golden ears".
