Power supplies ?

[diviy]

I know you can buy upgraded power supplies to different bits of kit ,So anyone tried a lab quality power supply thats has adjustable volts and amps so anyone tried one and what where the results ?

Anyone ?

Yes, a power supply when designed correctly removes as much ripple from the incoming rectification as is possible, it makes that direct current available in usually lower regulated voltage and current form.

Rectification whilst commonly done with diodes can also be done with valves, or even mosfets using the excellent LT4320
integrated circuit.

Common so called regulators are the 78XX series, but these are poor for audio use. Rather a combination of series and sometimes shunt regulation achieves better results. The best types of supply will have both voltage and current regulation as well as extensive protection as well as load sensing and correction.

A study of Walt Jungs excellent articles is a must. http://www.waltjung.org/waltsblog/regs/

Results with these types of supply, in my opinion are always far better than off the shelf so called regulators, or for that matter what is offered internally in audio equipment.

Hope that helps. Cheers / Chris

Cheers Chris so is that a yes or no as I have very little knowledge of electronics give me a engine any day of the week.

Hi Gerald
Yes its a Yes

Funny you mention engines, I had many years building Mazda rotary engines.

A few good places to learn a bit about electronics online is
Colin Mitchells Talking Electronics http://talkingelectronics.com/te_interactive_index.html
Colin has a practical approach which helps you to build circuits.

Or if you are into books https://www.amazon.com/Art-Electroni.../dp/0521809266
is a pretty good place to start.

But electronics is also about finding new ways of doing things too.
