inexpensive begining?

[captainpabst]

i've recently purchased some vintage hafler equipment ( Dh-220 amp, p-230 amp (extra set of output mosfets per channel) dh-330 tuner, and dh 110 preamp.

anyway i;m interested in a good "beginner" kit or so that would do at least 50 X 2 @ 8ohms and run at most $300 for everything.

purchasing pcbs would be prefered, and a full on kit would be lovely (though unlikely)

can anyone point me in the right direction?

for a backround on my capabilities:

good with bicycles
good with comps (hardware and software)
good with speakers (built a Adire Audio Shiva sub and some monitors)
good with soldering


thanks
-Eric

any one have experience with the basic ef kit, also would it be best to have it as a monoblock amp? or run both channels off of one transformer?

If you aren't going to use the hafler dh-220 amp, I built a leach amp for my first amplifier project, in a case very similar to the hafler case:

It is a good first project, and the boards cost $25 for a pair. You might be able to use the same transformer (the voltages should be similar).

that case does look familiar 😉 . However i love the hafler, maybe i should look for a busted hafler amp on ebay and then build that into it?

what was the running cost on that?

btw looks very sharp and neat inside *envious*


i do know a company that sells the chasis (i know at the least the bottom ($20) and maybe the top). but that looks very similar.

I picked up my chassis from a company that is licensed the hafler design and is selling the old amplifiers with newer components and a couple of modifications. They were nice enough to see me just the chassis.

I also picked up an old hafler dh-200 a couple of weeks ago, that I am considering gutting to put a leach amp in:

It isn't hard to do, and just requires making some brackets to adapt the mounting holes. Here is a picture of the brackets that I made using some sheet metal and a jigsaw:

If you can find an old DH-200, cheaper with burnt boards, the power supply voltages are almost the exact same as the leach amp. It would be a pretty cheap project, just buying boards, stuffing them with components, pick up some new input and output jacks, new power supply caps and do some wiring.

could you post a link for the Leach amp? looks like i found my project....

how much did the chassis cost you?
