Round Back Alternator Rebuilder

I had mine rebuilt by Sound Starter and Alternator Rebuild. Been in Tacoma, WA since 1974. Excellent work, easy to work with. A one man shop and it's all he does. soundstarterandalternator.com It's a local business for me so if I can be of any help let me know. I specifically wanted a stock amperage alternator after a misadventure with a pretty alternator that turned out being over 100 amps. He tested all my cores, labelled them by output and rebuilt the one that I chose
What I'd really like to do is get the output at various rpms for some of the factory alternators.
Then we'ld have a baseline to judge others on.

FWIW I have a VAT 40 so can check output for an alternator that's on a running engine. If someone needs and is in the area, we can do that.
