September 29, 20205 yr Had a Vodavi phone system at work that one of the station ports didn't work. Normally I wouldn't even bother trying a repair on one of these and just replace the unit, but lacking any working ones on the shelf, I decided to have a go at it... and somehow actually managed to fix it. 😲 Random picture of one off the internet for reference: I had to replace one of those little blue transformers, the thermistor beside it, and some smd components on the back of the board, with ones I salvaged off a different broken unit. It took a few passes to track down everything that was damaged, but now it works as it should. Yay.

I've been in dire need of a bench for a while and started cleaning my shop in earnest this weekend to make space. I haven't had a proper shop since we started building the addition on the house in 2016. It sucks!

October 18, 20205 yr Just put up some shelves and cabinets in the shop space preparing for making things again!
October 20, 20205 yr Author It seems to work great! I am not a huge fan of using a long screw driver to attach the top - having pre-drilled pilot holes would be nice. Other than that; it’s bolted to the ground and super stable. I sanded and put a coat of finish on my phono preamp faces just now! Edited October 20, 20205 yr by luvdunhill
October 20, 20205 yr ^^ Thanks. I've got more cleaning to do and then need to measure and do some layout but there's definitely something like this in my future.

Tomorrow I am going to cut up some remaining Baltic Birch ply to make some frames for speaker grills. That will involve a bit of clamping and screwing here and there. So, stay tuned!

October 21, 20205 yr Author All worked well. Sliced up the ply into 1” strips and then used the pocket jig to make a frame. I think 1” is too narrow so will probably do 1-1/2”.
October 22, 20205 yr Finally got around to installing the replacement IEC inlet / EMI filter on my spectrum analyzer. Hit the power button and it powered up as it should, thank satan. Then I ran a signal into it and the results were a bit... strange. It displayed the frequency way offset from what it should be, and there was some weirdness in what was displayed, and the problem was the same on both inputs. So I went into the self-test menu and most stuff was fine, but every test for the digital filter board errored out. Oh dear. It seemed fine and reseating it didn't accomplish anything, so I spent the next couple hours with the service manual, checking voltages, clock signals, data lines, etc. Everything seemed to check out fine. Everything suggested it should be working. I decided on a whim to run the self-test again, and... it worked? Hooked it back up to a signal, and... it's fine now? Wat. I dunno what the actual problem was, maybe one of the other boards I pulled in the process of checking things needed to be reseated, maybe it just needed to warm up for a while longer to shake off the cobwebs, who knows. All I know is it's finally working again, and all it took was a $16 part, so I'm happy.
October 22, 20205 yr It seems quite obvious to me what happened. Brent must have put biscuits in the oven, which started the Earth's magnetic field to shudder, but then he started grooming that enormous head, lost all track of time, and the biscuits burnt, rendering them not worthy of consumption. Therefore the Earth's magnetic field returned to normal. Elementary really.
October 23, 20205 yr The replacement input jacks for my Fluke dmm finally showed up. When I desoldered the old ones, I found something that wasn't as it should be, and perfectly explained the problems I'd been having with the meter. A $20 part this time, and another piece of test equipment is back in working order.

I didn't realise fluke had put prototype micro optical isolators into just some of the input jacks... Edited October 23, 20205 yr by jamesmking
October 23, 20205 yr Just fixed my recently sold Linn Basik tonearm on an Ariston RD80 deck. Buyer rang me to give me the great news that he had loads of white noise and couldn't get anything from the right channel! Ooops!! Picked it up off him and found that when the cartridge had been fitted, the sprung pins in the tonearm/headshell connector were gummed up and weren't springing back. Lots of solvent spray and a bit of persuasion from fine needle nose pliers. Woohoo! Problem solved. Happy buyer and even happier me. Can probably afford a better camera now and post better pics!
