Grizzly Posted August 8, 2021 Posted August 8, 2021 Item: "Powertran 75" Price Range: A smile and some manners Item Condition: Used Extra Info: Ive had this for over 10 years, with the best intentions of having it checked over and fettled, but have to accept the fact that it's never going to happen. Seems a solid, well designed and built kit amp with silly DIN connectors everywhere and some unusual controls. No idea if it even powers up to be honest though I have no reason to believe it won't. Take it as a restoration or tinkering project. Can post at cost, but no guarantee of operating condition. Please don't forget to report your post as FOUND when possible.

cheekyboy Posted August 8, 2021 Posted August 8, 2021 (edited) Hello Ant, Dale's dad built one of these amps back in the late '60s or early '70s and I spent a lot of time listening to that system with the Linsley Hood amp..........brings back good memories and it was a very good amplifier too. I've also got the 20 page detailed booklet by Powertran Electronics with an article written by Hi Fi News plus a lot of build detail with schematics etc included, if you don't already have it to go with the amp? Cheers, Keith A few pages from the booklet. Edited August 8, 2021 by cheekyboy 2
audiofeline Posted August 8, 2021 Posted August 8, 2021 MM and Ceramic phono inputs, which gives you the versatility to accept the output from a cheap Crosley turntable It should be possible to carefully cut some thin aluminuim sheet to fit into the push buttons on the front to replace the two that have fallen out. The selectable frequencies for the bass and treble are a reflection that there were lots of non RIAA records around when the amp was designed. Treble/bass was commonly used to get the best out of these LPs. It's why the World Record Club records (often licensed from European labels) would have a graphic on the back cover so the owner could mark their preferred tone control settings for the album.

Brian C Posted March 16, 2024 Posted March 16, 2024 I built one of these in the mid 70's and am in the process to tidying it up ( Recapping, etc.). At the time I modified the design to accept a tape return path (via a dual line amp that I got from my work at the time - Helios Electronics Ltd) but will probably reinstate it back to the original. The only problem is that I have mislaid the original Powertran kit instructions. I note that Cheekyboy has posted an image of exactly what I'm looking in 2021 for so I am wondering if we can get in touch. Here is a photo of the work in progress. 1
