d1stewart Posted November 16, 2014 Share Posted November 16, 2014 I have a Variax 500, the kind with the battery box for 6 AA batteries. I'd love to put a JTV-style battery into it. Does anyone know if this could be switched in for the stock battery box? Quote Link to comment Share on other sites More sharing options...
Charlie_Watt Posted November 17, 2014 Share Posted November 17, 2014 It probably could be done but you would have to modify the guitar body to make it fit. It won't drop in. Quote Link to comment Share on other sites More sharing options...
snhirsch Posted November 17, 2014 Share Posted November 17, 2014 If the six batteries are connected in series, that means the 500 is expecting a 9v supply. JTV batteries are 7.2v. Quote Link to comment Share on other sites More sharing options...
jegler Posted September 21, 2017 Share Posted September 21, 2017 If the six batteries are connected in series, that means the 500 is expecting a 9v supply. JTV batteries are 7.2v. Can I just plug a 9 volt battery in place of the AAbrick? Quote Link to comment Share on other sites More sharing options...
psarkissian Posted September 21, 2017 Share Posted September 21, 2017 Yes,... 9-Volt in place of the AA brick, a number of people do that. JTV battery won't work,... what snhirsch said. 1 Quote Link to comment Share on other sites More sharing options...
eenymason Posted September 27, 2017 Share Posted September 27, 2017 Can I just plug a 9 volt battery in place of the AAbrick? You have to use a top quality 9V - cheapies don't last very long at all, in fact some don't even get it to go at all..... I use AA rechargables, which I believe only put out around 1.2v each, so all up there's 7.2v output, but they work well, and last well too. In theory, I would've thought the JTV battery would work, so I don't understand why they won't - maybe it's a conspiracy? Quote Link to comment Share on other sites More sharing options...
psarkissian Posted September 27, 2017 Share Posted September 27, 2017 Not a conspiracy,... just a different species of Variax. And so there are different requirements. Quote Link to comment Share on other sites More sharing options...
jerseyboy Posted September 27, 2017 Share Posted September 27, 2017 2S (2qty cells wired in series) JTV battery pack discharge voltage curve is in the neighborhood of 8.4V-6V. Legacy 500 6qty Akaline sled can begin around 9.9V and in my testing and experience with Vax 500 reaches LVC (low voltage cutoff) somewhere around 7V. While it’s possible to operate 500 on 2S 18650 lithium ion/poly battery pack it will likely cut-off somewhere short of the full available capacity of 2S lithium ion/poly pack. But as long as proper VDC polarity's observed there's not much risk of harm running legacy Variax on 2S lithium pack. It's just that it probably won't be able to use all the capacity of the 2S lithium pack. 1 Quote Link to comment Share on other sites More sharing options...
psarkissian Posted September 27, 2017 Share Posted September 27, 2017 Do not use rechargeables in an older Variax. Certain IC's of that era don't respond or work well in a low battery volt situation, and can become damaged. It is not meant to be used that way. If the processor board gets damaged, it might not be repairable. And I don't know if there are anymore replacement boards available, should you damage the board. Don't go there. Page-3 of the user's manual specifies Alkaline batteries. Don't deviate from that. Line 6 does not support modifications to its products, and doesn't not endorse self repair on its product.
