hi folks-
I recently acquired a Kustom Commander. From the serial number its a 1972 model. Its in nice shape and sounds good. The speakers in mine (not original) have no markings on the labels to indicate the ohms. Anybody know if the Commander was fitted with 8 ohm speakers or 16 ohm speakers?
Thanks. Nice to know this group is here!

Hey, welcome to the place.
According to the manual, the Commander should have speaker part number 038-5008-00, 16 ohms, wired in parallel. If the speakers have been replaced, I would check them to see what impedance they are, so that you know if they are right or not.
If you have access to an ohmmeter, you can test the dc resistance of the voice coils to find out what they are. The dc resistance will always be slightly less than the rated impedance, so and eight ohm speaker will read something like 6 or 7 ohms. a 16 ohm speaker will read 14 or 15 ohms.
Tell us more about your amp. What color, how you got it, etc.
Again welcome.

Thanks Chicagobill for the welcome and the information. A manual, wow, that would be nice to have. Any chance that is available electronically?
I came by this Kustom Commander last week via our local Craigslist. The guy who sold it to me said he owned it 15 years and used it with his Fender Rhodes piano. No clue how many owners before him. I was surprised in all these years to find nobody had changed out the ungrounded 2 prong plug. I'll save it in a drawer but I'm changing to a grounded cord with 3 prong plug.
I was in high school and college when Kustoms became all the rage. I stuck with Fender back then but always thought the Kustoms were very cool. So when this one came up I felt the pangs of old memories and snatched it.
I was told by the prior owner that its color is "charcoal". The serial number is 88679. With the exception of the speakers everything appears to be original and I was pleasantly surprised to find everything works great including the reverb, tremolo and vibrato. The tuck and roll and casters are in great shape too. I guess they knew what they were doing when they offered a lifetime warranty on these!

Kool, most of us here have similar stories about a longtime love of the tuck and roll, so you should feel right at home.
If you look at the literature section of the site, you will find some of the original catalogs and spec sheets that cover your amp. It will be under "Other T & R" and "Combos". You can also look at the original Kustom color samples to see if the color is in fact Charcoal.
If you use the search function on the forum, you can find a serial number chart that will give you a close approximation of the date that your amp left the factory in Kansas.
I don't have a copy of a user manual for your amp, but I can get the schematic set for you if you want it. Just PM me your email address and I will send it out to you.

Thanks to all for your welcomes and information. I changed out the 2 prong power cord for a grounded 3 prong power cord. I also found the replacement speakers that were in the Commander when I bought it were 8 ohm speakers. I replaced them with 16 ohm speakers I got from Avatar Speakers (they have pretty good prices btw). I was even able to sell the 8 ohm speakers locally on Craigslist.

You are absolutely right about the LOUD aspect of the Commander. I thought mine might be so loud because of the 8ohm speakers wired in parallel that were in it when I bought it. But with the 16ohm speakers it is still REALLY LOUD!! No plans to sell mine. I hope to use it with my band if my back can tolerate the heft of this thing. (fat and loud are not a good combination in people but it works well for this amp!)
