[Hallicrafters] Re: SX-62A Questions

Don,

It's been awhile since I overhauled my SX-62 but here are some things I 
remember:

Don't use orange drops.  They're just too big.   Use high-quality axial 
lead caps.

You'll have to draw pictures of some of the wiring because you can't do 
one-at-time replacements everywhere.  Things are just too cramped.   I 
might have my old drawings if you need them.

A huge number of the resistors were out of spec, almost all of them.  
Be prepared to replace a lot of resistors

Before you go crazy in the RF deck, try the radio.  Those micas in 
there are nearly impossible to access and in most cases still OK.

There are some funny paper caps with braided leads.  I got an 
explanation of those caps from a real expert.  I've forgotten the 
explanation but I do remember the advice.  Unless you're pretty sure 
they are leaky, leave them.   There are only a couple of these.  I got 
this advice after I replaced mine and my radio works so there you go.

Some of the alignment slugs are sealed in wax.  There has been a lot of 
discussion about how to get the wax out and back in without damaging 
things.  But lo and behold, those slugs are right on the money 99 
44/100% of the time so the best thing to do with these adjustments is 
leave them alone unless the radio won't play.

The tone control caps  tend to short and take out the audio output 
transformer.  Don't neglect these even though this might seem a 
relatively less important part of the radio.

Be really careful cleaning that monster band switch.  There have been 
reports of swelling from spraying in cleaner -- a real nightmare.  Some 
have been lucky but some have been unlucky.  I would recommend a pen 
dispenser, not a spray can for doing this.

If your slide rule dial is damaged, someone makes replacements.  Excuse 
me for forgetting his name.

Many radios have moved from the bench to the operating position and 
back to the shelf or out the door in my shack.  But the SX-62 isn't 
going anywhere.  I love this radio.  I hope you like yours too.
