[Hallicrafters] Slow starting SR-160

[K4PRF - Burton Pratt]

This little transceiver has been sitting on the shelf for nearly twenty 
years and I finally decided to try to bring it back to life.  I have 
replaced all of the electrolytic capacitors including the 30, 30, 10 
multiple can.  I have three PS-150 power supplies which I use with other 
rigs in the SR series which  have been updated and work fine.   After a 
normal cold start of about two minutes with all the heaters on and the 
meter settling to the left it takes about another ten minutes for the 
little three bander to wake up.   Then the receiver and transmitter 
works fine.  I am thinking that the oscillator is slow starting.  I 
know.  Check the tubes, pin voltages etc.  Tubes are good.  It is 
practically impossible to safely check the voltages from the bottom and 
I have some test sockets ordered so I can check from the top. Another 
clue is that the crystal calibrator and the VFO are also off until it 
decides to wake up.  I have had several contacts with the little 
Hallcrafter and the reports have been good both signal and audio.  I 
still have more trouble shooting to do including touching up the 
alignment but thought some you might have run across something like 
this.  Any ideas?
