sfbp Posted August 10, 2009 Report Share Posted August 10, 2009 I am looking at the service manual for the JB930 deck here.I just saw one of these go for the vast sum of 26 GBP. My question is: it looks like the necessary hooks are there (page 44) and that a couple of components are needed like a capacitor or two. Is this mod within the reach of your average techie?I have a parent arriving in about a month and if another one pops up, I want it. But only if the mod is easy to do.Avrin?

Avrin Posted August 13, 2009 Report Share Posted August 13, 2009 (edited) You'll need to replace or rewind the power transformer. The transformer for the AEP/UK model is different from that for the US/CND one (see page 61). Other region-dependent components are much less important.It may be easier to buy a suitable AC converter.

sfbp Posted August 13, 2009 Author Report Share Posted August 13, 2009 Thanks. I unearthed one that produces 223V, hopefully that will be enough I was hoping for just a different tap on the Xformer, but I guess that is not to be. Quote Link to comment Share on other sites More sharing options...
Avrin Posted August 14, 2009 Report Share Posted August 14, 2009 223V should be enough. Quote Link to comment Share on other sites More sharing options...
sfbp Posted August 14, 2009 Author Report Share Posted August 14, 2009 Yeah. output is nominally 230 but the power in this old house is more like 117, so not too surprising it's below spec.My bigger worry is 60Hz vs 50Hz though the spec explicitly mentions both. I assume the "special for UK" designation on many units has something to do with particular mains noise? I recall hum was always bad when I recorded stuff way back when.

Avrin Posted August 14, 2009 Report Share Posted August 14, 2009 The different mains frequency shouldn't be a problem. Quote Link to comment Share on other sites More sharing options...
