I want to up date the circuit breaker and whistle diode in my LW transformer. I copied the numbers that Jim Barret gave us in the magazine. But i can't find the paper.

LW circuit breaker is 22-39.
I should have stated more clearly what I need to know. I want to upgrade to a faster acting circuit breaker than the original and add a solid state replacement for the whistle diode. Jim Barret had articles in the magazine giving Radio Shack part numbers. I can't find the paper that I wrote them down on. Does anyone know them or know the run of the magazine iwhich they appeared?
Obviously I misunderstood. My apologies.

I am looking to update my zw and kw. what would I use for them.
The whistle diodes Jim Barrett recommends in his video are the NTE 5991 stud mounted, anode to case, 40 amp diodes. I have been using them in my rebuilds and they make a big difference compared to the original disc type.
There was a thread back a month ago or so where some of the guys are having good luck using zener diodes.

As for the breakers, I have been using ones found at the automotive stores.
I am using a 15 amp breaker in my ZWs, 10 amp breakers in the KWs and 6 amp in the 1033's with no problems and they trip instantly.
As for the LW probably a 10 amp would do.
Good Luck!
Thanks everybody for all your help. Martin no apology is necessary. I should have ststed what i wanted more clearly
I got the ones from digi key #pb-188-nd 7 amp for about $3.00 and they work great. Hope that helps.
I was wanting to install some circuit breakers on my layout and I was wondering if someone could tell me if this circuit breaker (mouser 693-T9-311C-8) from mouser electronics should work ok ? It's rated at 8 Amps 240voltsAC 48volts DC. It seems similar to digi key #pb-188-nd which rsfulton said works great. However I bought one (from mouser) and put it in series with the track wiring but it does not trip even when I make a direct short on the track. Anybody have any ideas why it doesn't seem to work?
Mine trip almost every time I have a derailment,or short.
So does it trip immediately? Or does it take some time to trip, like a minute instead of seconds?
