Dynakit Stereo 70 Refurb

Codefox1;

Yes, that will be one of the steps of the restoration. Also the leaves of the transformers need to be brushed with a wire brush and repainted too. There is still a lot to be done. I just sent another order to Mouser Electronics for some additional resistors and some electrolytics for the power supply. I plan to use tubular electrolytics under the chassis and will probably leave the existing can where it is. The existing electrolyic began at a relatively low 360VDC at the filter section the output of the choke connects to and gradually increased to about 390VDC over about 10 minutes. I do not trust the existing can electrolytic.

As to what finish to put on the transformer bells, I might go with a different finish than the black normally used. I am considering using some of the satin nickel I used on the Philco 40-201 I restored. Alternatively there is an "almost chrome" paint available that would make the transformer bells look almost like the nickel plating on the chassis.

I plan to make some detailed impedance measurements on the two transformers before I install a new transformer. It will be interesting to see how much different the two measure in that way.
