why are old school amps worth so much?

Man, I can't believe you have a pair of PA6050's still in the boxes.
Some more... that sounds plain silly.

And here I was proud of the one I have. It's not genetically attached like the Zapco's, but it IS my only Autotek. Trades?

Trades? Need some PA6050's ? Sounds fair... LOL ...
What does Tim need? Hmmmm . What can you use that I have?

I had one of those sanyo running my highs back in the day, thought it was the 100w one though. I didn't like it in the setup I had, looked cool though and my friend still has the EQ. I posted a pic here someplace, but think he dumped the amp in favor of my coustic amp-300s he bought. Nice stuff there in the photos, glad I don't know what all of it is then I don't want it, lol.

Guy had the old alpines that look like RFs with only fins on top I forget the #s, just look up sold alpine amps. Had the DIN cables too. Was 3518/28/25/23 amps. I just bought another 3555 so good for now (that will go in my car).

Yes the transistors came off my sansui and output dropped. I put another amp in and later I soldered it back up and thought what a half* amp; the transistors fall off and this clamping system is nasty, on top of that it has some proprietary speaker plug you can't get.😀 It is pretty compact though, and it didn't blow up with the outputs falling off running a sub.
 
I actually like the Sanyo PA6100's. Yeah, they're rough around the edges (literally), but offered a lot of power for the money if you could spare the space.

Not that I'd use one these days, but the first triamp/subwoofer system I installed used three of them back in summer 1984. It ended up sounding very good, won the first (and only) contest it entered, and spawned a rash of local guys suddenly trying to keep up with this system. Fond memories.

Sansui ad from Nov '88:

An externally hosted image should be here but it was not working when we last tested it.
 
I just couldn't get enough power out of the 100w sanyo, otherwise it was fine. A 300w amp worked, though I had a blaupunkt that worked too at 120w. Still have a pair but one still blown need to finish fixing it. Odd amps but had some redeeming qualities like working really good on IB 10s. I remember being able to blow a 30A fuse on the battery with blaupunkt on four 10" subs and 100w sanyo on 6x9 and tweeters at the time.

That huge sansui, I can buy three of these for 205 shipped each: http://www.dakmart.com/product_info.php?products_id=5989 I don't know a thing about clif, assume just another cheap amp. Just though it was funny.
 
A good amp, but most certainly not "The amp that started it all"

It was sort of a new start for MTX, however. It was their first line of amps, introduced alongside the low-efficiency/small-box Blue Thunder speakers in 1988.

Unconfirmed Legend around my part of the world was that both series of amps were just another OEM job from PPI.

The dealer I worked for in 1988 was dealer and Distributer for MTX, but we were too busy and with Orion amps to devote much to these MTX's in the retail store.

BTW, at that time MTX's reputation was moderate. They produced a very large line of interesting, but less than top-of-the-line products. And the fact that they had no dealer protection compounded their lack of high-end reputation.

Anyone with a federal tax ID# could call up, say they're a dealer and order MTX products.

Whereas the likes of Rockford or Alpine required setting up a dealership, ordering a specific lineup and minimum of product, and maintaining sales to have the privelege of selling their products. Alpine even required that a certain % of eye level products in the demo room be theirs...

120375923151 here is a white one NIB .

He had 2 ,the first one went for $90.
I can't fault the guy but I so love these ads. $90 and this one is on there for $319. Dig this part:
"Just be prepared to have quality subs or this amp will expose their weakness by Unleashing RAW POWER!!"
Hmmm. Nice old school stuff, but a 1Kw class D it is not.

Man, PPI made everything!🙂 That sure looks like that worthless PPI plug too.

Hey is this Lanzar US made? 200314797480
 
Yeah, PPI and Zed were responsible for many of the new amplifiers showing up around that time.

Lanzars were Zed-built as early as 1988. I don't know when they ceased to be Zed products, or even if they ceased business altogether. Rodek and Crunch were also Zed products.

Autotek was the first Zed OEM products I know of, from '85-'86 or so.

Crutchfield brand amps were the first PPI OEM's I know of, also from '85-86.
 
A lot of PPI amps I've found out about lately. I have a sansui and a crutchfield now. I used the sansui a couple times but it never seemed to stand out.

Nobody really wanted this yamaha 350170819173 I have a crossover here someplace, I didn't like it years ago when I used it. Nobody wanted the ADS P80s, or the P120.

I almost sold/traded my RF OEQ1 the other day but kept it. Not sure how useful it would be without a RTA, or how clean it is, but with a LP PA2 and some old amps I could make a fairly nice retro system.
 
Wow, that IS cool. I do NOT remember PPI building Crutchfield amps that early.

That's a very, very early PPI. No silkscreen or soldermask on the PCB even. It's not even a re-design, it's just one of their own amps relabeled... I'm grasping for model #'s... PPI-100 maybe?

I'd say 1983/4, but the parties claimed most of the room in my memory for that (HS senior) year, so I can't be sure.
