Looking for a new Amp or Preamp? If you're after tubes, post over here.

You are correct about the output trannies but not the Power tranny

Ok the Power tranny is a little beefier but the outputs are about the same. Here is the quote off Bob's page.

2. The new USA made power transformer has a higher stack lamination than the original Dynaco power transformer and is rated
for 120 volts instead of 115 like the old design. The two tube heater legs are rated for 5 amps each instead of 3 amps each
like the old design. This beefed up transformer (which has a bottom plate like the original PA-060 to prevent EMI from
the transformer from reaching the audio circuitry) allows the use of KT88 output tubes in place of the EL34 tubes for
a slightly different tonal presentation. Four heavy duty neoprene isolation mounts are used to attach the transformer to the chassis.

3. The A-470 output transformers are brand new USA made custom production transformers. They use the same interleaved/layer winding
technique as the original cloth lead A-470's and incorporate the same high quality M-6 grain oriented laminations.
They are dimensionally accurate to the original design and have a durable heat resistant black epoxy finish.
