Changed out my fuses with new ones and have new spares, but would like to grab another set.  Any suggestions besides redding they are back ordered there.  Thanks

Same problem at HWA tonight looks like it is going to have to be sent to redding.   >:(

Temperature or vibration issue, of the VMS or battery?
Mechanical interference issues from running in a bag?

I'm not sure what the deal is I've tried 3 cables 3 different tekkeons and a Naztech.  I'm tired of fucking with it so it is going in for repair.  I guess I'll be running the PSP2 for a while.

Because I want to use externals and AA's as a back up!

For safety to prevent LORAs (loss of recording accidents) I power pretty much all of my gear pretty much all of the time from externals with internals acting as backup.  The exception of course is the one or two undercover shows I've recorded in the last five years or so.

Is it possible that having both the internal AA's and the external power supply connected is causing this issue? Have you tried running the VMS at home with just the Tekkeon and no AA's inside?

I used to run a VMS 5u with rechargeable Powerex AA's with no problems. It's just kind of a pain to recharge 8 batteries after each show, but actually never had a problem running that way.

Hope you get this figured out!

Ever get this figured out John? I have been running 9.6v 2,000mah NIMH RC batteries to power my VMS02ib just because they way my setup is now and its a PITA to keep taking my VMS out of the bag just to put AA batteries in. Normally I leave the AA internals in every one of my devices like Tonedeaf said as a backup, but DAMN I hate changing the AA's out on the vms. This past weekend at Summerdance, I didn't even put the AA's in at all, and just ran off of the external RC batteries. DAMN it felt good not to pry my vms open every day to change out batteries :) But I could just leave the same pair of AA's in all weekend since I'll be using external power, so I'll start doing that from now. The Tamiya RC plugs are shit though. I was losing my VMS signal at the beginning of day 3 but noticed immediately, and luckily was running my mk4>pfa>70D so I had that as a backup 8) And the issue was from a shitty Tamiya plug connection :( I bought some different connectors that I'm going to put on all of my RC batts so that I have a much more durable connection than a Tamiya plug :P ;D

I LOVE the RC battery route so far! And for local shows, I can just usse my RC batts. Like CK said above, I noticed my vms using juice when it was OFF too, so I just keep my RC batts unplugged until I get setup at the venue! And each 2,000mah RC battery lasts about 15 hours with my VMS02ib :) 8)

Hopefully you get this figured out cheaply and quickly! I am dreading sending my mk41 caps to Germany, but one of them is 35 years old and never been serviced :P I can get some new Grey mk41 housings though while they're home lol ;D Might be cheaper to sell my pair and buy a new matched set?!?! Anyway, please let me know what happens with this, because I'm very curious!

Sent it to Germany to get fixed.  It will be gone for a few months.

It might not take that long.  I've had stuff out and come back in a month.  It kinda all depends on when Redding gets enough stuff to justify a shipment.  If you happen to send your stuff in right before they send a shipment, it will definitely be less than three months before you get it back.

The boards had to be replaced due to battery acid damage!!  I never had batteries leak so it happened before my time.   Just an update since I had a few folks pm and ask.

That is really unfortunate. What'd they charge? Did you get the damaged boards back?

It wasn't cheap and didn't get the boards back.
