Use a heat gun instead (or a rework station). No need for flames.

I've ofter throught it would be a good thread to have showing photos of recycled parts used to build amps, power supplies etc.

There is a guy on Ebay UK who sells empty equipment cases - including some military with the guts taken out. I got a few HP pulse generator cases from him and they were great for housing power supplies for my Class A Power Amp. They are built like a tank and also had some extra goodies like power switches etc.

Cheers

Mike

Default Ebay link?

Hi Mike,

Do you maybe have a link to this ebay seller, please? Many thanks for the goodies, now to make time after work to get down to things. Though first busy testing & "profiling" BJTs small, medium and large with my new DCA55. This is a process that needs lots of space and containers.


On track though - I have managed to get hold of quite a number of not economically repairable UPSs at work. Lots of inductors, but most especially heatsinks to be had. A few componnts may be salvageable, but most of these have blown FETs and/or caps. Most are 8 to 10 years old so the electonics is generally too olde to be harvested. I have never thought of reusing the cases though. Will do so in future though, as these are normally soildly built blighters.


Kevin

Hi Kevin,
the ebay seller is mjtronix but he is on ebay UK and I am not sure if he ships internationally, but worth a try.

I eventually bought 3 case from him as I got a good deal and he was a good guy to work with.

I have attached some photos showing the cases:

the first is the raw case with the inner rails etc removed

The second is the Class A power supply installed (Transfromer, mains DC offset remover, softstart circuit and smoothing board)

The third is the final result looking cool. - sorry about the crappy photo

Best regards

Mike

Default Test equipment photos

Thank you for the replies. Here is a few pictures. I just need to learn which parts/Components to spend time on and which ones go in the bin. Bourns, mills, dale, switchcraft, helitrim, are some notable brands. I am currently digging for heatsinks and power supplies for my upcoming ACA project-anything I can do to mitigate the exchange/duties and lower my cost.
Thank you, Almo

I have though about this, especially for certain areas of the world that donít have access to parts through the same channels as most of us.

I know whenever a device is put out to pasture in our house, it goes through the shop first, and whatever can be quickly removed is saved in a bin for experiments or use even.

Another hint for re-using stuff is to look on Ebay using the search for "Amp for spares or repair" or similar, as you can get very good chassis and components that way.

Also, look for items located near you that require personal pick up. They will usually have less bids and thus be significantly cheaper.

Cheers

Mike
