Re: [drakelist] TR-4

Check the power supply electrolytics, check the diodes. Jumper the power supply plug without the TR-4. Does the fuse stop blowing? You need to isolate your problem. It could be many things. Could be a short in the plug where the wire goes into it. You need to do basic trouble shooting so you

Re: [drakelist] TR-4

Did you ohm out the diodes in the AC4? If not, try that. If those are ok, try jumpering the pins in the connector that turn the power supply on.(don't remember which ones right off hand, but you can see in the manual) and the plug the AC4 in by itself and see if the fuse still blows if so , w

Morning, I've developed a "crack" in the pre-selector knob, on a otherwise mint 2B...Must'a tightened her down way too much after the cleaning...40 year old plastic can be pretty unforgiving to us brutes Anyone with a "parts" rig with a good knob they care to let go ?? Rick K9RSW --

[drakelist] Hum

Hi All, I got my TR-6 this week and noted that it has a hum in the audio even with the volume control completely down. I am going to look at the filter capacitors in the AC-4 today, but thought I saw an tip somewhere that there was another place to check, that can cause AC type hum in the speaker.

[drakelist] Re: no spot tone on SSB T4XB

Andy, The spot function puts out a signal in a mode determined by the function switch setting.  On CW and AM you'll thus get a carrier to zero beat.  On SSB you won't.  What you get is an SSB signal to spot.  If you talk into the microphone in spot mode you'll hear your voice.  But if there's no

Re: [drakelist] T-4x Carrier Osc, Filter Match, Bal. Mod Question

gm all, I found by playing with C-2 that it was balanced with no output. It appears the null at 0 out is the correct setting. Moving C-2 to either side gives a good increase to the sideband associated with it. I tried the applying the same logic at T-2, T-3, & T-14. It did not work. No increase

Re: [drakelist] tr7 oscillation, predrivers blown.. My drake b-line twins are laughing!!!

Craig, I am interested to see the responses you get. I am helping a friend with one doing exactly the same thing, except the drivers didn't go out, he had static (or lightning) take out some of the PIN diodes, he replaced them and now has the same oscillation problem. I am going to re-check his

[drakelist] no spot tone on SSB T4XB

I just got a nice T4XB the other day and this is my first Drake equipment. I'm using it with an old SX101A and have the receive antenna out on the T4XB hooked up to it. My problem is I can't seem to get the spot tone to work on SSB. It works fine on AM and CW. What could I be doing wrong? The rig
