A couple of disclaimers first:

a) I know diddly/squat about Ham equipment. I am not a Ham.
b) I have been noodling about with vintage equipment, tube & solid-
state for now over 30 years, so I am familiar with the species. What I
write below is a generic approach to (re)starting vintage equipment
after some years at idle.

sounds good

Just to add. In the days when boat anchor stuff was the normal gear,
when items had been on the shelf in storage for long periods, the
electrolytics were not so good then as now

Switch on procedure from storage was:

1. Expect the odd "phut and horrible smell." It *will* happen at some
time.

2. Switch on for a few seconds and then off - allows the
electrolytic barrier in the capacitor to start to re-form - the number
of seconds for certain equipment was specified - otherwise about 5
seconds for the first time.

3. Switch off for about 60 minutes.

4. Switch on for 10 secs and then off for 30 mins.

5 Switch on for 30 secs and then off for 30 mins.

6. On for 30 sec off for 10 mins.

7. On for 60 sec off for 5 mins.

8. And so on....

These were valuable equipments and the manufacturer normally laid down a
procedure. The whole idea being to re-form the electrolytic capacitors
and to give other problems time to cool down for inspection and
detection/rectification.

The alternative was just to switch on and then stand back from the bench
with your fingers in your ears and a handkerchief over your nose

And so, like all good "tinny and bull****" sessions, we come back to
the original question - if Dave hasn't wandered off, in boredom or
disgust. And like all good amateur arguments, we have suggestions
ranging from ludicrous to....ludicrous.

We have had - an engineered, high tech solution
A stuff it, just power it up solution
The KISS solution - use a light bulb in series
The do it slowly and painstakingly with a metered variac solution
Some reminiscences about the "old days"
Someone else offered to buy the radio, but got their models mixed up.
Answers from people who, well, really....dunno why....

And all valid, all correct - so, Dave - take your pick which one YOU
use.......alternatively, there is a TS520/530/820/830 group on Yahoo.
You could post your question there - they have heaps of people who
lovingly use, restore these old radios - mind you, the answers will be
as broad spectrum as here, and LOTS more off em hi hi.
