MRC CM-20 service tech needed

Tom, MRC repaired my CM 20 years ago. They are near me in Edison. Why not contact them about the repair?

Hi Chris,  Thank you,  Yes, I have had very satisfactory experience with MRC repairs over the years, alas no more. 

I spoke to them on several occasions, they only want to sell me  new ones.  They refuse to  service the CM-20, 6200 or the 9500.         

I did get the defective part but am hesitant to attempt installation and  kill it,  I do not want to melt the thing.  Actually there are seven CM-20s that I have needing service.  I have borrowed  some 6200 packs from TT service to use on the RR in the interim.  

The various branch lines can be combined to run the RR on two packs but the wiring provides for optional individual control at each town and each yard for either DC or AC.

Tom, can you send a pix of the part in the transformer needing replacement? where it is soldered in too?

Thank you for your follow up Chris.  There is a yellow CAUTION tag on the silver metal bag stating "electrostatic sensitive devices"  with instructions to "Do not open or handle except at a static-free workstation".    I believe I should leave that for a qualified tech.    

There's a wristband that the person wears and jumper wires for the soldering tool and any 3 third hand jigs and such. basically, everything must grounded.

No big deal. 

Contact a local computer repair shop. They do that type of work all the time. Well, at least one that does component replacement.

perhaps you could persuade gunrunnerjohn to take the job.

Tom, the TIP36 (hopefully it is a TIP36A, B or C) is a generic PNP power transistor and is not particularly static sensitive.  That said I will replace it for you.  It is not a hard job.

This is an easy repair, find someone local so you don't have shipping.
