RCI-2995 DX HP Factory Error

[BayouRadioAmplifier]

on the TDA2003. pin-3 is common ground, and also common with the backside.
no need to insulate. (usually, maybe) I was using these devices in modulators
years ago. I would just bolt it to the chassis with a light coat of heatsink
compound, since I designed it all for the chassis to be RF ground as well
as DC ground, which is normally the case.





so you can just get a metal washer, with the right thickness,
and width to cover the back side of the TDA2003
to mount it for better heat transfer. Also, it may not be
getting that hot.
(nothing like them modualtor/regulator
transistors in them RCI/Galaxy radios!)

But! this will put the radio chassis at DC ground at this point.
The power supply goes to earth ground at the wall outlet.
Should be no problem, on paper. and you may have your
coax shield grounded to earth and your 60 Hz 120 VAC line.

I have not received a response from RCI as to how they will resolve the defect on my two radios and all other radios. I am curious how RCI would correct the defect if I were to ship the radios to them.

Bummer.
Ranger will likely tell you to ship it to Chris @ Superior CB for warranty repair.

Just fix it and save yourself some shipping.

I agree. Just a few minutes ago I shipped it out to the person who purchased my other 2995.

This guy has aluminum-nitride TO-220 washers. Just sliding one of these (with a layer of compound) under the part would take up the slack, remove the air gap and be the most labor-effective answer IMHO.
