I have two good 2B's and a parts unit. Only the parts unit is bent but
that was the result of being dropped hard (which is why it's for parts).

If the shaft was hardened it would probably shatter or shear off if
bent. Could the tension of the dial string cause a bend if it sat for a
very long time without being used?

When your ONE job is to deliver a 4" long 1/4" steel shaft without bending it..... :-)

I agree, tt's hard to picture it being bent after being installed.

?I, too, suspect a slightly bent 2-B tuning shaft may be a factory installation of a defective part, occurring at some tiny percentage of production output.

I cannot imagine any kind of damage or force applied in situ - shipping damage, bench top abuse, dropping the radio, etc. - that could cause a steel shaft to go out-of-true but leave everything so delicate and sensitive around it perfect and untouched. This couldn't be the result of damage-in-place. Had to be installed that way.

If one can't just tolerate it and live with knob wobble and occasional dial slippage the only fix is a tear down, attempted straightening and reassembly, and dial restringing.

Ugh.

Funny thing, my 1st 2B had the same problem! I pretty much did the same. Remove the shaft, tap is straight, reinstall and restring. I wonder if it was a bad run?

Steve,

I'll have to check those.

Check the values of C50 through C52.? It wouldn't be a bad idea to check the resistors around the tuned circuit, as well.

Cranking up the output of the generator helped and I can hear it better on any/all band settings (was only hearing it well on one of the AUX positions but can hear it now regardless of the bandswitch which makes better sense). Also, moving the VFO doesn't affect the zero-beat now.

The problem I'm having now, though, is that I cannot zero-beat a 50.000kHz signal by adjusting T7's slug.? It is quite a bit off frequency and not sure what would cause that.

Make sure that you have it on the right pin. I used about a 1V signal and had no trouble.?

Following the manual, with the BFO and PRODUCT DETECTOR on, I've connected a 50kHz unmodulated signal through a blocking capacitor to V5, Pin 1. While I can hear the signal, if I turn the tuning knob, it changes the zero-beat and that doesn't seem correct to me.

The manual doesn't give any "initial settings" for the alignment so I'm curious how one is to zero beat that oscillator. Is there something wrong with my 2-B such that tuning the VFO changes the zero-beat for this step? If not, I'm unclear how to go about this adjustment and am asking for any advice regarding that.

The Reactive is the large knob on the Left and the Restive is the large knob on the Right.? The band switch is in the middle of those knobs. So after setting to the correct band which would be middle knob counter clockwise for 80 meters start with the right knob for a dip and the left knob for a slight rise and repeat.

I am not real sure as I do not have the low power version to check now but the large knobs may be reversed on it.??

You are at a big disadvantage trying to tune this tuner..? Here is the way it needs to be done.

After setting the band switch tune the Resistive Tuning for a SWR dip. Then turn the Reactive Tuning to the Right a slight amount.? The SWR will increase.? Then tune the Restive tuning for a dip in the SWR.? If lower then repeat the process.? If higher , tune the Reactive tuning to the left and then tune the Resistive tuning for the lowest SWR.? Repeat the process several times if needed.

This seems to be similar to the way a tube transmitter tunes up.

The low power version tunes the same way.

Very different than most tuners I have used.

Is it normal for the 2B S meter to sit at about S3 with power off??
I can zero it OK with power on, but it always rests at S3 when the?
power is turned off.?
