HP 204C

Post by MED6753 »

Another Facebook Marketplace find. hp 204C Sine Oscillator. Bargain priced at $25 USD and it works. It will be going into the project queue. Somewhat dirty on the outside but won't require paint. It will be getting my standard electrical restoration.

Quick peeks on the inside. It's built like a tank.

Well that was easy. 15 minutes with some cleaner and the exterior is done. Electrical restoration at a later date.

Nice find! $25 can't be beat for a working HP oscillator.

Any thoughts on replacing the missing HP logo? Those little badges look like they were prone to falling out and going missing over time with that build style for whatever reason. Brittle plastic breaking or adhesive not standing up over time? I don't know what the cause is but it looks like a frequent occurrence with that era of instruments.

Junk HP equipment beyond hope and plugins turn up from time to time. Things like power meters without the probe are worth very little, but are good for feet, knobs, screws and other bits and pieces. The style and size of those logos may have changed over the years, but it should be far from impossible to find a replacement, even though it might take time for one to turn up.

Yep, if I had a junk unit I'd replace the logo but for now it will be naked. :D

Somewhere in the æther there is a pocket that's full of old style Clement cabinet feet and those tiny badges, as they so frequently are missing...

I've found those little HP badges are stuck on very well. I've never tried removing one, but it doesn't seem easy.

However I'm convinced there is an alternate universe into which some of my socks disappear and some socks from there appear here.

hey med

a small envelope was dropped off at the post office this afternoon.

was gonna put it in a small box.....but the word in the Commonwealth of PA is that new yorkers typically use small boxes to mail tarantulas to their enemies.

felt you would be more comfortable with an envelope.
