[ARC5] TCS RF ammeter or thermocouple replacement

I need a repalacement for my TCS RF ammeter -- or perhaps just the thermocouple, if that is replacable.
Of course I could always make a makeshift RF output readout using a diode (WS-19 style) and self- calibrate a panel meter (putting in a new face on the original or an other meter)  but prefer to keep the original meter.

I haven't opened the meter yet to take a closer look at the how the thermocouple is mounted -
I assume that once a thermocouple is overloaded, it's not reparable. I do have other thermocouples
of another type, which I could use and calibrate a new dial face -- again losing
the original installation.

My TCS-12 RF Ammeter hardly budges, even under heavy RF currents. The problem  appeared many years ago, probably, if I remember correctly, a result of drawing too much current while matching an antenna using an external variable capacitor across the RF output. I haven't used the rig in many years but now wish to reactivate it -- also remember that the RF Ammeter on my GF-11 had to be treated with caution.

If anyone has an extra TCS RF ammeter/thermocouple unit, please let me know.

Thanks in advance,
