content: There have been some discussions about creating a database containing reference information regarding the linear power supplies produced by Power Designs, Inc. Please see the original thread on the topic for background.https://www.eevblog.com/forum/testgear/looking-for-goodinexpensive-bench-power-supply/While the original thread was largely focused on the "precision" models, there is considerable interest in the forum in tracing out a better history of the company. To this end, we are asking for the contributors to the original precision thread, as well as those who have yet to contribute, to provide information about their units that we can collate. Barbouri's model in the prior thread was a good one, as he included the serial numbers, the geographically-tagged logos, and preponderance of the dates of internal components, as well as other pertinent information. If you have a variant that doesn't look like the other pictures, we want to know that also; some of them have been repaired and/or modified, some are actual factory production variants, and the latter distinctions are likely important to putting together the pieces of the PDI puzzle.Here's the format Barbouri used in the prior thread, and I think it's a good one to emulate, but of course the info is good any way you wish to provide it:Quote from: Barbouri on November 22, 2019, 08:39:58 pmIn the last thread some of the schematics were dated and from those we can also deduce when manufacturing may have begun for a given model. Another helpful piece of information might be the older cal stickers on the instruments, as we can then narrow down the individual date of manufacture further. Finding out how long some of the units were in production may be difficult, partially because there are so many variants even among models with the same designation. I am including all the models referenced in the prior thread below and current listings on auction sites, although they are not in chronological order yet. This temporary layout is so you can easily spot a model you own that isn't listed, is incorrectly listed, or needs to be added.Precision Models1001A1025P20052005A2005P201020202020A2020B (vertical variant, plastic enclosure variant, meter variants)2040A401050205020A605C400C500Regulated Single Output1010T1210-S15151515A1515B2015R20502100D25253206324036100R36503650R3650S40054010 (not precision model, but same model number)402040504050D50055005R5005T50155015A5015D5015S5015T503060106010D602060506050A6050B6050C6050D61506150DRegulated Dual OutputTW1550TW1570TW2525TW2860DTW347DTW4005TW5005DTW5005RTW5005TTW5005WTW5015TW6050ATW6050DRegulated Triple OutputTP1500TP1800TP325TP340TP340ATP343TP343ATP343BHigh Voltage Output1556B15702K10B2K203K10BHV-1545HV-1547HV-1579AYour additions and corrections are greatly appreciated, and I will soon be adding the relevant information from my own units to this thread.
