Shameless Kutztown Plug
 
The XXXVIII Kutztown Radio Show begins (officially) on May 11, 2018 at the Renningers Antique and Farm Market, Kutztown, PA ( http://www.dvhrc.com/kutztown.html ). This is a cast-of-thousands event, those of you who have been there understand. Those who have not, please have a look at the pictures. Although the show is primarily dedicated to vintage radios and related items, on offer will be:
 
• Audio equipment – tube, solid-state and hybrid. Last Fall, the offerings spanned from McIntosh to Revox, from AR to Magnepan, from Dynaco to HH Scott, and points between.
• Vintage TVs of all ages.
• Test equipment, tools, manuals, and more.
• Miscellaneous electronics and related hardware of all types, ages and conditions.
• Tubes, capacitors, parts, knobs, dial covers, repair and appearance parts of all types.
• Much more!
 
I will, as usual, be running a diagnostic clinic at the club table.
Radio Free Kutztown will be broadcasting on AM and FM-Stereo also as usual.
On-site camping is free.
Admission is free.
The Buy-it-Now section will be open from the beginning of the show.
There is a quality auction on Friday afternoon.
Fireworks, as usual.
 
We all look forward to seeing you there!

The horse is dead. It will remain dead. The stroke of the connected
activities, and in spite of whatever kind. Let it rest.

Therefore, the definition of sanity must be doing different things on
each attempt, which sounds much like trial and error.

In that light I cite the repetition ad nauseum in US schools that causes it to take 12 years for learning that should take 6.
 
>"Therefore, the definition of sanity must be doing different things on each attempt, which sounds much like trial and error. "
 
Sounds like research. An hypothesis is put forth and experiments are done. Repetition is only for confirmation and peer evaluation.
 
These protocols are not strictly followed anymore and leave room for doubt. This is what give AGW deniers ammunition in their illogic. This is also why I do not necessarily believe some of what they purport as "science" these days. which is better this week '? Butter or margarine.
 
If you want evidence of tampering with science look at Monsanto, which due to their follies in greed is now facing a class action lawsuit which they are likely to lose.
 
But they won't pay for it. The stockholders, employees and customers will.
 
Now THAT'S Usenet thread drift !

Those are nice, but a bit undersized for what I work on.
 
So I bought a 20 amp Sola "Harmonically balanced" (four
winding) constant voltage transformer. From about 85-145 v
it will hold a steady 120 v and a reasonable looking sine
wave.
I put a three position "center off" switch on the front
panel to select "Line Neutral" "Floating" or "Line Ground"
for the "neutral" line on the output.
Following that, I put a 20 amp Variac wired for 10% boost at
max.
Then came the metering.
0-150 vac meter, 0-30 amp ac meter, and a 4-wire 3000 watt
ac dynomometer or direct reading of the load in watts.
 
Just for good measure, all the cords, plugs and outlets
are rated at 20 amps.
 
I also have a 2500 watt 400 Hz inverter for working on old
aircraft equipment.
 
If you're going to do something, do it right.

That is the difference between a machine and a person.
 
The horse is dead.
It will remain dead.
Continued beating notwithstanding.
Let it rest.

I have a Vivitar 253 flash unit, it has two problems 1. The power leads to the battery terminals were corroded and need to be re-soldered. I can fix those easy. 2. one of the leads to the bulb for the calculation dial is busted right at the bulb, so I can't just re-solder that. I need a new bulb. its LT1 in the circuit diagram shown on this web page. http://www.repairfaq.org/REPAIR/F_strbfaq.html#STRBFAQ_069
 
Anybody have a lead on a replacement bulb? Thanks

I need the light bulb for the indicator dial, not the flash tube.

Ah, sorry - I believe those are common neon lamps (NE-2 or-equal).
