I have not used Duplicolor paint on a chassis, just on the transformer bells. I did use some Krylon satin nickel on a Philco 40-201 I worked on last year. Ron recommended that paint and it has just the right color and finish to look very close to the type of plating that Philco and many other manufacturers used on their chassis. It is a pretty durable paint and I would not hesitate to use it on a Dynakit or other amplifier if I did not want to spend the money for a new chassis or for chrome plating. After a chassis goes beyond a certain point of corrosion and pitting there is not much point it attempting chrome plating as the metal would have to be sanded and buffed to the point there would not be much strength to what was left to go through the plating step process.
I ultimately made the decision to get the stainless steel new chassis from DynakitParts.com It is a beautiful duplicate of the original in looks, but being buffed stainless steel the finish will hold up much better over time.
The unit sounds great with the new A470 transformer from DynakitParts.com I cannot tell any difference from the one OEM unit that is still in the unit as far as how it sounds. DynakitParts.com says their transformers are made to the original Dynaco specifications as to how they are wound, just that new insulation materials are used which have better resistance to flash-over etc. I have spent numerous hours listening to FM radio, LPs and CDs on it so far and find it to be much more realistic in reproducing music than an Onkyo M282 power amp that it replaced. I don't think I will ever go back to solid state after this.
