Just checking they didn't also install a mouse? He's an indoor cat and we don't have rodents so he has never seen one. But I've seen his hunting instinct kick in with the odd flying insect so I suspect any mouse would be a goner. After the dishwasher completed it's cycle I opened it so he could che...

It was actually a well thought out con. Freezer level temperature does affect the crystaline structure of some alloys. For example in aviation after annealling rivets they work harden at room temperature. This can be slowed by keeping them in a freezer. The treated fuse that blew quickly was obviou...

It's been off for hours but still needs another checkout to insure it's safe.

Our old dishwasher sprung a leak and building maintenance determined it needed to be replaced. So today a new one was installed. While maintenance was here Harley was locked up in the bedroom so he wouldn't get in the way (Trust me, he would). After they left I let him out and he immediately noticed...

It was a royal cussfest but the old filter caps are removed and new installed. Dremel with a cut off wheel was tool of choice. There's a few items yet to complete and then the PSU will be ready to install.

The burgers in the UK must have been real shitty because the burgers at McD's are far from what I would call decent.

The Strand is in the West End; that would have been deserted since most things would have been shut by law on a Sunday, except newspaper shops and corner shops. In some ways I miss Sunday being special, but not in others. There are some counties in New Jersey that still have Sunday "Blue Laws&...

The 5110 PSU on the bench. Removal wasn't so bad after all. But the fun part has yet to follow. Removal of those cans. Let the games begin.

Nope, I'm the asshole. You broke it, you replace it. And don't give me this "volunteer" crap.

Been thru that garbage where tools are "borrowed" and never returned or broken. Made me the asshole I am today.

Squeezing in some limited lab time among all the daily activities. This is the capacitor set for the 5110 PSU. The new filter caps installed in the 5 pin adapters. I will be removing the PSU from the 5110 to make it easier to work on. While it doesn't look too difficult to remove it's going to be n...

Orange LED tied into +5V and now the X1 position is illuminated on the 5A15N plug-in.

I have heard of this or one similar and I'm very interested to see how it works.

You didn't read the entire thread again, did you? The case was painted gray.

Repairs to the front panel. Replaced corroded BNC's. The binding post for the 600 Ohm output was cracked. Super glue fixed that. The plastic cursor to set accurate frequency was broken and missing. Made one with black paint. https://imagizer.imageshack.com/v2/xq70/923/L2ViiT.jpg The mechanical resto...

Finally had a good day to open Papa Smurfs paint shop. It's a matte vintage gray somewhat close to hp gray. https://imagizer.imageshack.com/v2/xq70/922/Ovh2g0.jpg The old handle was shot. New handle installed. https://imagizer.imageshack.com/v2/xq70/924/8sIlzO.jpg A few items left to fix on the fron...

Classic.

Of the Tek 400 series non-storage, in my experience in the UK, 475 is the most common, 465 less so, then 465B. I haven't come across a 475A or 485 on my travels. I don't see them on ebay either, although I don't particularly look out for them. I have seen some of the lower bandwidth ones rarely, bu...

I've had my fill of 465/475's. Too many tants and the attenuator switch decks are either always dirty or the main shaft is worn causing poor contacts. But I will consider more 485's if they come cheap. (Already have 2)

My bucket list? To wake up everyday. :lol: Seriously, these weren't "technical" but were on the list and achieved... Visit West cost USA....specifically LA. Was not impressed. Travel across Mojave Desert and camped out at rim of Grand Canyon. That was impressive. Technical.... Visited Nava...

Nope, they don't have the notorious RIFA's but they are loaded with the notorious beaded tants. Guaranteed that's what smoked.

The front panel cleaned up well. I used automotive polishing compound on the aluminum frequency dial and it got rid of 90% of the surface corrosion. The corroded BNC connectors will be replaced. Next up is cleaning the case in prep for paint. The actual painting may have to wait since it's done outs...

Next project. hp 211A Square Wave Generator. From Facebook Marketplace. Extremely dirty on the outside and the cabinet will need re-painting. Papa Smurf's paint shop will be opened and will spray it gray. https://imagizer.imageshack.com/v2/xq70/923/ise1vQ.jpg https://imagizer.imageshack.com/v2/xq70/...

My buddy. Jumps up on the bench and rubs his head on my arm asking to get a head scratch. Then he lays down and watches me.

Next up is the 5A20N Differential plug-in. The issue with low gain on the minus input was due to dirty attenuator switch contacts under that metal cover. Once deoxit'ed that fixed that issue. The plug-in pretty much works however DC Balance and Atten Step Balance need adjustment as well as a general...
