I'm a newbie here. First post. My goal in this post is to gather the attention of some knowledgable amplifier folks as in a coming/subsequent post I'll be asking for some advice in troubleshooting a Parasound HCA-2003. Now, on to my immediate goal.
Shown is my stretched, dual mono, heavily POOGE-2 inspired modified DH-200. What else can I say other than it's been performing nicely for the past fifteen or so years. I'm the original owner. I do possess a second completely stock DH-200 yet, in my laziness, have never directly A-B'd them. With lots of inputs and outputs to my 5.2 system, it's a rather time consuming exercise to do that. My bad.
The modded amp is used to feed the mid/tweeter housing of B&W 801-II's. (Two channels of the aforementioned Parasound amp are used to feed the B&W's woofers.)
I'd be happy to check back here to comments/questions. Maybe some folks here can guilt me into performing the A-B exercise (with the stock Hafler and/or the Parasound).

Neat! I still have an original DH-200 that I built from a kit back in 1980. Do you have the original Pooge magazine articles? I would love to read those.

Its 2 inputs, speaker terminals and line cord, unless you have it in an unaccessable rack swapping should be easy.
That's the guilt part, what else are you asking?
Its been my experience that the POOGE modified amp will be far superior to stock, not sure about the Parasound but I would apply POOGE techniques to that as well, that's where the work will come in....
Had to do some digging in my closet but found the Amateur Audio Issue 4/81. Will, in a couple of days, scan it and post here.

Audio Amateur and it's never ending 'Bodge' how to's.
Sucked in a Lot of naive readers ..myself included..
In retrospect those were Overly complicated 'rebuilds'
That imo... weren't actually near as good as suggested. Certainly so, given the perspective of time.
That's one overpriced mag I Do Not miss.

I don't disagree. One thing it taught, not directly but by inference, is what was "in" $2k+ two channel amps. That helped to avoid dropping many K's of $ on placebo effect purchases.
I miss that mag if only cuz back then we had one, maybe three-ish sources of self appointed guru-experts. But now (internet era) everybody with an opinion is a self ascribed genius master authority.
