Uffda Wrote:Ron, since you brought up the bucking transformer I have to ask: Is there any danger in using a variable transformer like my Isotap or big honking Powerstat as a dedicated 110V outlet? I promise to exercise the knob regularly.
Phil (Uffda) - If your Variac is a nice, hefty unit, I suppose you could use it on a regular basis (as far as I know). I would feel better with the bucking transformer setup, though, for long term use.
I guess I wasn't thinking clearly Ron. Even if I use it at 110V, I want to be able to power up for modern stuff. Your way will work
better for a daily driver away from the bench.
By the way the Powerstat is 12 amps.
I love watching the transformation. The notebook is such a valuable resource. Your 70 cabinet is telling me to contact Mr. Jones about a de-shame job on my 90 or 70 or both.
Ron I saved this pic for future use when I restore my 655B cabinet. Best photo I could find of one
FYI the model 640 has "650" stamped in ink on the back of the tuning capacitor frame too.
Wow I would have to install a polycarbonate back and have it lighted to show that all the time. Its so beautiful. I hope to do that to mine when I'm done
Very nice restoration indeed Ron !!! Congrats!!!
