Is there anyway to by pass the board to run this in forward? Or can a different e-unit board be used? From another company?

You can use a standard electronic reverse unit, or you can just wire a bridge rectifier to the locomotive pickups and the motor it i'll run in forward only with no sound.  Either is a fairly trivial exercise.

Finally, it's probably possible to repair the PS/1 boards, I know that George (GGG on OGR) does a lot of these, you might contact him.

That is weird.  WHat transformer?  Most PS-1 are flying at 14-16 volts.  They move nicely even down around 10V.  Board can be replaced if not repaired for much cheaper.  G

Yes Sir, Had the issue a couple years ago if you blew the whistle it would stop, you then had to move throttle up to 16 volts then it would run. you then can bring it down to 12 or volts it was fine, its a z-400 mth transformer, In fact I got your email from gunrunnerjohn, will be sending you the boards this week. Thank You again. Mark

Just a quick note to check the 9v (8.4v) battery health status.  Do sounds cut-out in less than 3 sec when power is cut?  The PS1's can get "quirky" when battery health is low.

Nope, 2yr old battery this year, prior to using my batteries get charged yearly. sent board out 4 repair. thank you
