Heya, Forum. Anyone know much about Early Kiesel (pre Carvin) student model amps? Just got this guy & I've only found one other (on Carvin's museum site). Weird (to me) old radio tubes. Any info greatly appreciated.
Thanks!
-Pete

Lots of rust on that amp. Looks like it was
wet or under water for a long time.
Those amps are restorable. However if you have to replace the power and output transformers it could get expensive. If I was restoring that amp, I'd take all the parts off the chassis, sand blast it and repaint it. Of course you won't know the extent of the problem until you take the amp out of the cabinet and give it a complete inspection and test the parts. |

| I guess they figured you didn't need a volume knob on both the guitar and the amp! Definitely stored in a moist environment at some point. If it had been underwater I think the wood would have swelled and split the MOTS covering and there would be even more rust. Looks like some rodent action on the backside but the front looks nice. A good amp tech could restore this even if he had to draw up his own schematic. I agree with Blake, if the transformers need replacing it will probably exceed the value. Working vintage 5W amps seem to sell in the $250-$350 range on ebay. Someone with a Kiesel guitar would love to have it, I'm sure. |

blake sure knows his stuff. he has helped me with my amps many times.
i would add that if the tubes have the numbers such as 35 or 50, then you are talking about what they call a widowmaker. you may need to add an isolation transformer to keep from shocking yourself.
play music!

Yeah, that monster capacitor shield gives me the fear.

It's got a power transformer, so it's probably isolated.
I've read that it's tricky cleaning rust from transformer cores. Something about possibly shorting the laminations at the edges, increasing eddy current losses and heat. Anyone here have any info on that? I have an old Pro Reverb with rusty transformers in my project queue. |

We haven't considered the speaker yet. Damp storage and rodents are not friendly to them.
Also, if it is a field coil speaker, that is another problem. Again, several ways to cope with that.
Replacement with a modern speaker would require a
slight modification to the power supply.
To restore an original field coil speaker can be done by people who specialize in that kind of work.
Again: $$$.
I agree with Bill, probably damp storage instead of immersion. |

Yup. The wood that comprises the bottom of the cab is solid w/ a couple small discoloration spots & no warping. This thing was kept in a damp/humid environment at some point.
