I'm not being picky or critical Mudfoot,,,,, But an EFHW wire antenna is not a dipole.......as you may know......

If I was doing this repair.....these are parts I would automatically replace..... Of course along with the two power transistors, Q3 & Q4 ..... 1) .... R5 , R7 , R8 , C10 & C12 ..... If not there, install C11 & C13 ...... 2) .... Check for correct value C9 , C14 , C19 , R6 & R9

I don't want to swap, because I already have a FT101EE...... But I do have an immaculate RCI-2995DXCF (original owner) that I'm willing to sale...

I always operate my station with TWO power/vswr meters..... First one between the transceiver output and the amplifier input, AND the second is between the amplifier output and the antenna input...... Actually my second meter is inline after the amplifier output and before the antenna tuner...

Yeah, wishful thinking....

That is exactly right.....

Above is the input "bandpass" filter capacitor that is missing in your amplifier..... This is the input tuning capacitor above, tuned for lowest VSWR on the input from radio into amplifier......

Zoom in on the relay area..... The colored diagram you show above is not the correct one to look at. That is for the amplifier with the old oscillator board installed. The second diagram is the correct one....... As I mentioned before, there are many parts missing that have been removed in the...

I'd like to help you, but I hold on to any Texas Star parts as they are hard to come by,,,,,,,

Yeah, they probably were bad. Alway, always, when replacing the power transistors, always replace the 10 ohm and the 1.6 ohm bias resistors.....They can be bad even without looking burnt. It is cheap insurance to help protect the transistors.

As much solder that I see on the board in your initial photo around the transistors, there is a possibility that some solder has "leaked" through the small weep holes and dripped straight to ground........ When I am rebuilding/refurbishing an amplifier, especially any Texas Star amplifier, I...

Here is some guidance....... I hope it helps you.....

Well, you definitely will have a project on your hands........ It has definitely had more than one set of transistors in it, probably several sets.... Can it be restored ? All it takes is lots of time and money..... Yeah, but it really needs to have some very experienced hands in there...... I...

You can always have the book and materials to refer to if you need any information...... BUT, to take and pass the exam test for the license, you only need to study the materials that are actually on the test. As you may know, the test question pool changes every few years. But the actual...

You are studying incorrectly.....

In addition to my comments above, you can do as I do with my station...... IF your antenna tuner has (as my Palstar HF Auto Tuner has) two or more antenna connection outlets, then connect the dummy load (as I do) to the other antenna output connector on the tuner and do away with the antenna...

You do not need, nor do you want the antenna tuner before the dummy load........ The dummy load is already a tuned antenna on all the HF bands......

Last thing inline right before the antenna........and after the antenna switch....... Remember, the antenna is being tuned to match everything in front of it....... You do not need, nor do you want the antenna tuner before the dummy load........ The dummy load is already a tuned antenna on all...
