Troller Power Pack?

[Anonymous]

My brother was recently given a Troller power pack.It wasn't working and he discovered that one of the rectifier diodes was blown.Where could I find schematics or possibly part values for this brand?My brother says that the output is 18 volts and is rated for 12VA.I have tried to find information on this brand name on the net without sucess.I seem to remember this name being around in the late 70's or early 80's.If anybody can help me with this I would be most appreciative.

Have you tried Radio Shack? Troller has been out of business since the 1980s, unfortunately (I have a few Troller transformers as well, and love them).

I have heard that there was an article on repairing these several years ago. Anyone know where it was published or what year? I'll check with the modeler I heard mention this the next time I see him and see if he remembers. They were very good packs from what I know.

I can't answer your question, but I have a Troller Twin Momentum 5 and it is the best DC transformer I have ever had - still use it today. The momentum feature is unmatched, the power output is awesome, I have operated large layouts with it - amazing machine...

ANONYMOUS,

If you have a Radio Shack,near you,take a trip there and see if they have,cat.# 276-1653..that is a package of 25 assorted Rectifier Diodes,,one of those should fit,they should cost around two bucks..That power pack is rated at 12va, so it is not all that powerful,,about a 11/2 amp,,without seeing the components,its hard for me to give you any,for sure answer,,but I have a feeling,there is more wrong with it then a bad Diode.....for instance,is it a half wave Bridge circuit,full wave Bridge,,is it filtered??? Too many things to find out,,without seeing it..

Cheer,

' Anonymous' means the member that made that post isn't here anymore and the account has been removed. Since the thread was started twelve years ago it's a fair bet they no longer need an answer to their question.

Try Radio Shack.  Any diode rated for 50 volts or better and 3 amps or more  will work.  Radio Shack also sells "full wave bridges"  which are four diodes in a single package.  If your Troller is old enough to have a copper oxide rectifier (large item with a lot if big fins) ,  I would replace the whole thing with a full wave bridge from Radio Shack.

Interesting, I was not aware that a poster's "forum name" became "Anonymous" on their old posts or threads if they were no longer members.  That makes it harder to start a "whatever happened to ______" thread if you need to find a particular rememberd old thread to recall their forum name.  

2001, those were the days.  -- perhaps only Erik Bergstrom should be allowed to edit or lock this thread!

I think it depends how and when they ceased to be a member.  Remember the forum software has had major change/upgrades at least four times since this thread?  And I believe at two of those times we had to re-register.

My question is how / why does a twelve year old post get brought back to being a current topic ?
