|  |     Not sure if it's a fluke, Bob.  A friend of mine had a Polytone and
    gave him nothing but *grief* until he finally decided to dump it.
    
    Also, I don't think that I can ever recall hearing any "good" things
    about Polytones.  Only bad things!
    
    Sorry!  But it doesn't sound like you got a lemon (or 3 of them), but
    instead, an engineers nightmare.
    
    FWIW,

|  |     My Polytone Baby Brute was DOA when I received it ten years ago. The
    day it arrived, I was going to do some recording and stupidly took it
    with me without testing it first. Since I was desperate, I disassembled
    it at the studio and found the external speaker jack wires were
    shorted, so I cut them out. Then I found the speaker protection mesh
    was rattling, so I ripped it off.
    It's been working fine ever since!!! :-):-). 
    
    I wrote a rather hostile letter to Polytone, who called me to apologize
    and offered to repair the unit and extend my warranty. I never bothered
    to send it to them.
    
    My MB IV is five years old, has moderate amount of use and has not had
    any problems. I generally only use these for rehearsals and recording,
    so I couldn't say how they hold up under serious gigging. Most of the
    Polytone users I know have been happy with them. I like them because
    they sound good for their weight, but, because of my first experience,
    I'm not sure about Polytone's quality control.
    
    When I do * serious * (;-)) playing, I use Fender.

	My personal opinion from a hardware design viewpoint is that
the problems you've described are potentially connector problems from
what I know of the insides. One of which you mention(no reverb)happened to 
my MBII. It turned out to be a broken wire at a reverb pan jack. It took me 
15 minutes to fix. As far as any smokey experiances,I've had none. 
	For a lightweight practice amp or for occasional jam session or 
recording session they work fine. I've  used mine for a monitor amp with my 
Mesa preamp...A keyboard player I was playing with used it for amp for a 
couple of practices.
	I also had the screen covering the speaker and I ended up taking it
off and restapling back on so it was tight across the speaker.
	So I'd say the amp has held up pretty adequately for what it is.
	As far as servicing them? they are no big deal to fix,most of the
parts are off the shelf.....And schematics are available. They are probably
the most basic solid state amp you can buy today....
