[ATM] My Mototrak V stopped working... what will I do?

["Christopher Dalla Piazza" <dalchri@hotmail.com>]

I'd hoped that it would last forever but...

It does not appear to be producing enough power to start my RA drive 
anymore.  I have noticed that two of the transistors are getting very hot.  
These transistors were pointed out to me earlier by JMI in determining if I 
had the 5W or 10W model.  Because these transistors were small, I had the 5W 
model.

The drive corrector also emits a buzzing sound that increases/decreases with 
the frequency of the current as I press the east/west buttons.  It's hard to 
isolate but it seems to be coming from the transistors.  It has been making 
that noise for awhile and I can't be sure that it hasn't always made that 
noise.

I am praying that the problem is one of the simple components and not any of 
the smarts that is built into it.

The reason I am so set on fixing it is because I don't know where to get a 
drive corrector anymore!!  My mount is not integrated with a corrector.  All 
I need is E-W AC, and N-S DC control with an autoguider input.  No one seems 
to sell one.  So, faced with having to possibly build a replacement, it 
can't be harder to fix what I have.

Does anyone have any ideas?  I am completely dead in the water for imaging 
until I find a solution.  Any pointers to products I don't know about or 
basic electronics troubleshooting would be greatly appreciated!
