Cheaper way to get a Line 6 Variax Cabled Power Kit

Recommended Posts

I'd say that, unless there's a significant difference in what you're expecting to read and what you see,  you'll be in good shape.

 

My experience has been that the output of AC supplies, such as the ones for your XPS mini, is generally not that close to the rated value, and is  often a little higher. (not in your case, though...) More significantly, it usually goes into the first stage of an on-board power supply -- almost always into a full-wave or bridge rectifier to convert to pulsating DC, then filtered and regulated by a semiconductor device to create the actual operating DC.  The raw ac voltage from the transformer can also be somewhat dependent on the incoming voltage from your house wiring. Very unlikely to be a problem unless it's way out of whack.

 

Battery voltages are nominal, depending upon type and age. NiMHs are different from Alkalines and nicads. A tenth of a volt is not unusual to see, and it's certainly not a problem. Again, the first thing that an incoming voltage -- ac or dc -- sees is often a voltage conversion or regulation circuit. The actual operating range for consumer equipment is very likely to be + or - a volt or more. They have to account for sagging voltage from batteries before the performance starts to degrade or cut off entirely.

 

Good that it zeroes on your resistance ranges, but even it being off a minor amount there doesn't indicate a significant problem. 

 

I'm betting that it will be just fine to perform your testing!

Thanks so much again!   I'll press on and see what happens! :-)

If you wish to have a direct link with me, you can do it via Gmail.com, with cbrillow being the first part of the address. I'm always happy to keep in touch and was very pleased to hear that your project worked well!

 

Yeah, that works too, and is easier than using separate parts!

 

My gosh, I guess my first Variax is around 18 years old, or so. I ordered it before they actually started to ship to music stores! The one that I built the power supply for is a 600 that I bought in around 2007 or so. (and probably have played it for less than a couple of hours, total...) 

 

Don't have any idea about the newest line of the Variax, those made since the sale to Yamaha. Maybe they have eliminated use of the XPS?

 

Take care, my friend, and drop me a line via email, if you'd like..

It's good to have a direct contact. As we see, one changing in forum functionality - and contact is lost.

Sure, I will text you via email to show results of my project!

Please do come back here with your results. I'd be very interested.

 

I'll do the same :-)

I have already told you about my results a few messages earlier (about xps copy in a box). In that message I meant that I want to show it to cbrillow, because I made it with his help, but the  conversation with him via direct messages was suddenly lost and I had no chance to show what I have built.

Ah ok. Sorry. I misunderstood
