Does anybody own one of these? What kind of wattage should you get out of these little 1 pill's?? Are they used as drivers for bigger boxes?
Thanks

Typically 100-120w output, yes they are usually used as driver for larger amp.

671-
Thanks! Does Copper sell these Tx Star modulators or not? I looked but didn't see them.

Also, did Copper drop the 667V?? One time, I was looking around the Copper site and found the 667V under a totally different category than amps for the mobile??? Maybe I'm wrong?? I have searched the Copper Talk Forum to get an idea of peak watts for the 667V,... 500-750W??? Is this right?
Thanks

Forummaster-
Didn't see the modulator under this section??

Thanks

Forum Master Note : We stopped stocking the modulator because we were having around a 30% failure rate.

that is a typical failure rate when people overdrive those little things(the mod v's). you can't dump full power of a radio into them and expect them to last long.

for the 667v, they run 'clean' up to about 525-550wpep. semi-clean to 600w, and on the dirty side after this(with max power below 700w).(another amp that you don't want to put much power into)

What kinda dk and swing for the modulator + is recommended? I was thinking about just running the modulator ONLY. Can it take a little swing from a General Lee or a VR9000???? These swing to about 40+ easy.......:)
Thanks

Set your radio so the ModV keys 25-30w.

Tech671-
I put my General Lee inline with the TX Star Mod. and when I turn on the pre-amp, I lose receive. When I turn it off the receive comes back (stock radio receive). I put a different radio inline and the pre-amp works just fine and gives me additional receive and is loud.

What is happening here??????????

Also, I can only adjust the dk for the modulator to about 10W with 1W dk from the General Lee. It swings to about 110W on a Dosy though with this wattage. Why can't I adjust the dk any higher on the modulator??? I have the TX star modulator plus with the internal knob "dial a watt" knob inside the modulator. I didn't get any instructions with it so does the dk from the radio need to higher,... say 2.5-3W's???

THanks

Ease the internal adjustment of the General (AM low power adj inside) up to 2w. This should bring modulator up to 25-30w.

I have seen that problem before but have no clue why it does that with some radios?!

Thanks 671 & Carolina!
I'll try adjusting the dk,... I kinda tinker with stuff but the modulator swings to about 120W which is pretty nice for how much $ I paid for it. Well that kinda chaps me about the receive though. I just bought this modulator to get outta the neighborhood a little bit. I usually use my General Lee and Palomar 250 in the mobile, pre-amp works fine in it.

Thanks for the replies
