[Drakelist] R4B No Standby or Mute
My B-line has been working but today that after hooking it back up (was working on a TR-4) I noticed that the R-4b was not muting or going into Standby. In standby or ext mute (w/o short in RCA Mute)audio is distorted RF Gain only raises S Meter to 20 over or so. Something seems to have changed since I used it last a few weeks ago. Could this be a tube failing or ?? ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
Re: [Drakelist] R4B No Standby or Mute
Paul - Same result if you unplug the MUTE cable at the receiver? FAST and/or SLOW the same? Possibly bad V1, V4 or V5, unplug one at a time. Does S-Meter go up to full scale?

[Drakelist] Drake 2B anomaly
I have a Drake 2B that I refurbished and re-aligned a few months ago, and it plays pretty well on all bands. The only thing that seems a little strange is when the passband control is set to "1", and the preselector is off-tuned or if there is no antenna connected (low atmospheric noise), it sounds different than the passband control is set to "2". It's hard to describe, but it sounds a little like it wants to whistle or oscillate or something like that. Maybe a little "tinny". (It doesn't really oscillate though). Another weird thing is that it is mostly just with the AVC in "slow" position that it sounds like what I've been describing. When the AVC is in "Fast" position, Passband 1 and 2 sound a lot closer to each other. When I'm listening to stations or a high atmospheric noise level (AVC Slow or Fast), the problem, or anomaly is not very noticeable at all. I positioned the passband knob so the pitch is pretty much the same at positions 1 and 2 on all three selectivity positions, although it was a slight compromise to get them all close. I have a friend that has a 2B, and he is experiencing the same thing. I guess it's possible that they all do that, but I had a 2B back in the 60's and 70's, and I don't remember than happening. I probably wasn't as fussy when I was that young though. This isn't any big deal, but I was just wondering if anyone else with a 2B ever noticed what I described, or maybe someone with a receiver that has a similar passband control / selectable IF filter circuitry.

[Drakelist] SW-4, SW-4a
What is the selectivity on the SW-4 and SW-4a? Are they exactly the same radio, because they seem to be? ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
