Wrenn & Older locos

[AMJ]

Today I have finally got round to chipping the Trix Flying Scotsman. Done it with a Bachy 2 function chip. Wired motor & feed as usual. as it uses just a bulb for the lights have wired this between the blue & white (head light). Success.

 

Having a look at the other locos that have not been chipped I am now thinking do I chip the Wrenn BR Standard 4 tank? It was nominally replaced by the Bachy one some time ago. Yes I know how to wire it up but would like thoughts on what chip should I use? I realise that it's a power hungry loco. Lenz Standard?

I have one old Wrenn chassis still running, and that has a Lenz Silver, which extracts performance from it never previously attainable using a feedback type DC controller. Had the Lenz standard been available at the time this is what I would have used, it has the same drive. That's not to say there are not other decoders up to the job, a suitably rated Zimo for example, but I think the Standard is probably the cheapest for refined performance.

Thanks 34.

Looks like I'll call in on the way home from work next week to the model shop that I pass en route. Unless I wait for the Bachy 03 to arrive.
