Hello,
I've always wanted to refurbish my own amplifier. My only experience w/ a soldering pencil is making my own cables and soldering in drivers and already packed x-overs. I know how lethal electronics can be and that capacitors need time to drain, but I would like to find a very simple amplifier design to refurbish/update with better parts: caps, resistors, wires, connectors, etc.
As I'm attracted to tube sound something simple w/ only a few tubes would be nice but not citical. Could be a pre-amp, integrated - something simple but good sounding. Transistors would be fine if not complex. Any recommendations from valued members?
Best,
Barry No. 2:cool:

You could do a lot worse than having a look here http://www.audio-talk.co.uk/phpBB2/index.php
There's a heavy DIY bias (pun intended ;) ).
Quite a few members there are regulars here too.

Not sure if of any interest but you could try a Musical Fidelity X-series.
X-can or X-pre share similar mod path and are covered in depth by rock grotto
http://www.rock-grotto.co.uk/morecapacitance.htm
Upgrades listed from upgrading caps, replacing volume pot to building a very simple PSU.
Mods are pretty cheap to carry out (say £20-40 for components for main box and another £30-40 for PSU if you wanted to go that far. Plus of course original purchase price). The mods are pretty clearly described and parts listed (takes a bit of research to source your own similar) or just buy the kit with instructions rock-grotto sell.
Most importantly the mods provide distinct sonic benefits and you can clearly hear the effect of different components (especially with headphones).
The above gave me a bug for DIY modding.

Tubes can be nasty, dangerous things to be playing with. Read up on the safety of it all if you want to give it a go. It can be a very quick and easy way to become dead.
I've got a couple of tube amps that need a refurb, but I'll wait until I get some better insulated meter probes with clips before I even think about it.
I second JP's recommendation regarding Rock-grotto and doing up old X series products.
The original MF X series was well designed (by mr De P I believe?) and make abroad I think. The improvements wrought to my X10-D by the upgrade were significant and made it far more transparent to the source too, but without stripping the sonics clinically bare in the process IMO. I also made up the simple 12V AC power supply he suggested, but this page looks to have gone from the site now and I don't think I saved the page intact. The X-10D works on a 12V line so is safe as houses to work on and practice one's soldering skills..

Thanks Dave R and mark - sage advice. I'll look for the "X's" by me. The folks on this site are great resources.
Best,
Barry
