I'll hope the power supply in your "older VTF2" is OK.
I had 2 of the older VTF2's and both power supplies
went bad. You can bypass the auto on/off, I just don't
know how to do it. You can call HSU at 800-554-0150
and maybe they can help you. When my first
VTF would not play (red light on all the time) I took apart
the sub, thinking it my be a fuse or something simple
like that, but no such luck. I live 60 miles from Anaheim
(their headquarters), so I took the sub to them, and they
said the power supply was bad. They could fix it for $100
or so, or upgrade it to the new and improved power supply
for $150. I opted for the upgrade, and had them bypass
the auto/on/off (green led on all the time). The upgrade is
actually pretty nice, sub has goes deeper faster (more slam)
24db per octive verses 12db. Same thing happened to 2nd sub.
Anyways, since you origonal post was on 10/3 and last reply
was on 10/19 I figure you hopefully have the problem fixed.
I just am replying to help you out, or anyone else who has had
this problem with this paticular HSU sub. I'm a little upset with
my experences with the VTF2's (naturally), but I'm still happy
with the sound........they do make very fine subs.
