Dynaco A10 rebuild
Easy Runnin

Unfortunately for me, I inherited some audio equipment when my brother passed last December. It included a Sanyo quad receiver, a Phillips turntable and a pair of Dynaco A10 speakers.

After doing a little research and for sentimental reasons I decided these speakers were worth a rebuild. Thanks to various internet posting and especially advise from Dave and Jesse I was successful in my rebuild.
For the crossovers I used an 8 uf Sonic cap and a 24 uf Solens cap along with mill resistors. I also put in new Dayton binding posts. Next I stripped, lightly sanded and stained the cabinets with a dark walnut stain. I top them with 3 coats of wipe on poly. The grill cloth is burlap from Jo-Ann fabrics.
I’m real happy with how they turned out. I got about 10 hours burn in on them and they sound pretty good. The first test was Workingmans Dead and they passed. Next up was Robert Cary’s Midnight Stroll. The bass was a littler lacking, but I guess that should be expected. Overall they seem like a very nice speaker especially considering their size.

well, that is too bad.
The A10 is the one classic Dynaco loudspeaker I've not run across in the field myself. I've never heard one. Opinions on them are mixed, I but I have to assume they're at least pretty OK.

Good job, I'm sure your brother would be proud of your restoration.Political Correctness'.........defined
