Isspro amplifier box?

[jeff77indy]

I've found an used Isspro R3807 egt gauge along with a R6713 boost gauge for what maybe a decent price.
But the seller can't find the thermocouple probe and I haven't heard back about the amp. box. I've also e-mailed Isspro about replacements. But with it being Sunday, I figured to ask if anyone here had an idea if replacements were available? Do they need to be a matched set?

Thanks
Jeff

I have an electric oil pressure gauge from them and the sender is whacky. They told me it would not read correctly even if I got a new sender from them. So, before you spend any money talk to them.

Thanks;
I did hear back that he has the amplifier but can't find the thermocouple. So I need to hear from Isspro on this.
I replaced the mechanical fuel pressure gauge in the wife's '01 with an electrical EV2 and it's gone wacky on her. I plan on going back to a mechanical when time and $$ permits.
