[Drakelist] TR-4 Audio Hum Question

2014-06-02 Thread Alan Adelman
I have used the Hayseed kit and it is very simple to install.  You will 
need a high wattage soldering gun or other comparable device (not just a 
small pencil-type iron) for one one of the can caps.  As somebody else 
mentioned, you should test the PS using a voltmeter before you attach it 
to your TR4.  Especially make sure the bias voltage is correct.  While I 
was in there, I also replaced all of the resistors with modern types; it 
only costs a few dollars in parts and 30 min of labor.  You then know 
that your PS is in good shape all-around.

[Drakelist] WTB: AC-4

2009-04-09 Thread Alan Adelman
I just got a T-4X to keep my R4A company, so now I'm looking for a power 
supply.  If anybody has an AC-4 (maybe an AC-3 if it's in good shape) they 
would like to seel, please let me know.  If you have an MS-4 to go with it, 
even better.

Thanks - Alan, WB2ERJ, aade...@yahoo.com

[drakelist] Re: Dmm recomendations

2008-07-17 Thread Alan Adelman
Many thanks for all of the info folks.  I've ordered a Fluke 115 which I'm sure 
will satisfy my needs for quite some time.  BTW, I do not yet have a Drake but 
would like to acquire a 2-line (I only work cw) when I finish with current 
products.

Thanks -- Alan


[drakelist] DMM recommendation

2008-07-16 Thread Alan Adelman
Can anybody recommend a decent DMM for use in maintaining my boatanchors?  
Something with a fair sized display for my aging eyes would be great.  My 
ancient analog VOM doesn't cut it anymore.  I don't need laboratory accuracy, 
just a reliable instrument.
