Classic gear from yesteryear; vintage audio standing the test of time.

RE: Heathkit AA150

I looked at Sam Kim's web site. It seems that his AA-151 rebuilds include a full conversion of the preamp to triode operation as well as modifications to the power supply and amp section. His most extensive rebuild includes the ability to switch between triode and ultralinear operation.

Point is that to extract the best from this unit, modification of the preamp design is needed.

Best,

Ross
