Pictures of my Leach amps

[pip]

Hij All!

I promised som fotos of my home made recycle Leach amps.
As told in an other thread http://www.diyaudio.com/forums/showthread.php?s=&postid=588071#post588071 I have no (very little) education or understand for eletronics.

Each kabinet contains 3 leach amps. 2 Low Tim for bas and treble and 1 super amp for midrange. It is combinatet with som of Elliott's projects.

So, my thank to Jens Rasmussen for starting me into amplifirebuilding! Dr. Leach for publishing his amps! Elliot for all his nice and "easy to understand" (allmost) projects. And last to all you here i diyAudio - Thanks!

My powersuply i startet with Elliott ESP's P39-softstart in combination with his P38 - signal detection auto power on unit.

With this I have a small problem - Something in my main supply can tric the circut. Perhaps a VDR-resistance can help with that?

My amps is sitting on heatsink of this type - The super amp on its own and 2 Low Tim on another - Bad with 2 amp on one heatsink?

The heatsink is placed side by side with an 80mm fan pushing i one end and an other 80mm puling in the other end.

The fans are regulated with Elliotts P42-Thermofan-control unit - one feeted from the main-rail thru Elliott's P102-simple pre-regulator ....

and one with a pure P42-fan control unit - Regulation the puling-fan

 

[pip]

and the last thing I have build in is Elliott's P33-speakersprotection.

That was it - Mostly made from computer scrap - It doesn't look good, but it sound nice.

One picture of my loudspeakers. The high one is the "La Folia" and the one beside i a dipol woofer inspiered by Monte F. Kay http://www.mfk-projects.com/dipole_sub-woofer_dayton_series_ii.htm - Thank for that Monte Kay!
