Amp/Chipamp kits and parts

jimbo1968 · 10:44 PM

I'm selling off all my part finished and un-started kits and parts.
Will add photos is due course.

Total of 10 toroidal transformers, dual 25V, 300VA.

2x LM4780 stereo chipamp kits. One built (has earth hum and/or oscillation problem).

2x LM3875 stereo chipamp kits. One built.

2x LM3886 dual mono chipamp kits. One built.

The built kits are in mdf boxes with aluminium side panels as heatsinks. They are awaiting steel lids which I could get made if required.

I also have lots of power sockets, switches, RCA sockets, and a few sets of binding posts.

Also lot of Neutrik RCA plugs and VanDemme instrument cable to make phone leads with. Bright Red, deep Red, and black.

Here are some photos:

I can break up the amps, and build extra boxes if required. Eg if someone wants 4 channels of LM3886 spread over 2 boxes.

I've got spare rectifiers as well if you wanted dual mono LM3875.

Hi Jimbo

Any idea of how much you want for the amps and parts??

Cheers

I'm looking for approx 50% of cost price. which bits are you interested in?

updates:
The 'unbuilt' lm3875 has been assembled onto the boards but not tested. I'll give your money back if it doesn't work.

There is only one unbuilt lm3886 snubber power supply, and two built ones. The unbuilt one has slightly taller caps than the current brianGT ones.

I also have two chunky black heatsinks that would make nice side panels (with the cut edge down). 1.3kg each. 250x150x30 with 8mm back panel.

This is what the mdf box looks like at the back, not so pretty but easy to build.

Also latest lm4780 configuration, it didn't cure the hum.

Going Fast !

LM3875 kit sold.

Note: the built stereo LM3875 (which has been in use as my bedroom system for a year) can be upgraded to dual mono as I have a spare ps kit.

I could use a pair of trafos. Anything you'd like in trade?

jimbo1968 · 25th June 2010, 09:40 AM

Hi,
I don't think it's cost effective to post trafos that far, i'll have a look though. Also it wouldn't be 25V in USA.

Whoops. Didn't notice you were in the U.K.

How much would you sell a couple of trafo (with shipping to France) ?
Can you send me your reply in PM ?
