why are old school amps worth so much?

[ppia600]

Wow, very cool. Wish I had the cash to bid on that one. I've always wanted blade

[jol50]

I'm in the wrong business! I watched a HK CA260 go for $75 and 12 shipping, not a bad deal. Looked ok and had some dust on it. Then I see another one (that ebay searched up for me) all cleaned up that looks about the same, for $225 and 18 shipping. I mean the guy would even make money on the shipping...for dust wiping. I would be amazed if anyone bit on that, but once again ebay does not fail to entertain.

Yeah that blade looked nice, anyone see what it went for? (I looked, 176 w/2hrs to go yet)

Tim, I think Polydax was still around in the early 90's. The "made in W. Germany" was on the back of the Polydax tweeters.

Here is my newest addition to the old-school collection. (smaller gold amp) . Separate PS and AMP on this model in the CP line...Still looking for more of them if anyone has some. Anyone???

Hey, that's good to know. I've been fond of Polydax since using a set of their 5" HIF13J's in some old Fisher home speakers in the 80's.

It was obviously an Audax HIF13J driver from earlier, so I assumed Polydax was just part of the French Audax line. Maybe they went another direction with Polydax later?

Beautiful CP's. Never got to work with them.

The 260 for $225 has been there for quite some time. It'll sell one day, but lately it's been too much of a buyer's market.

Anyone here ever use one of those small blades? They were extremely interesting when first introduced. The rep showed up at my brother's shop & claimed you could daisy chain them, power would be additive

The fact that they were so small and claimed specs to match most anything left an eternal curiousity over them. Seems like they used a similar power supply philosophy to Carver's "magnetic field" supply.

Hey Tim, ever seen one of these? Arrived today. Figured since you wear the Zap crown, you might know more about it. I have several of the faders, AEX crossovers, and a lot of the PX eq's. But have never seen this configuration...

[tomtomjr]

Here is another one. This one I picked up today. Local deal on this one. Here is what I was told about it, but don't know much else. This one's serial number is #6. Yes, #6. I was told that it was made for Kicker. Kicker was going to have US Amps build amps for them, but something happened and it didn't go through. Was told it is a 100HC. Really a neat amp. Very simple. Looks to have some power to it too. The "K" in the heatsink is what identifies it as the Kicker prototype. Don't know how much of this is true, but what I was told. Anyone have any input or info? ...

My beloved crown is but a statement, as you own the kingdom.

Nope, never seen that. Looks like it would be set up for a sub + midbass + front & rear biamped seperates. I can't imagine why the PX would be on the bottom, I suppose the volume control was left preset.

A very nifty rack, indeed. I'm amazed at the variety of factory produced one-off custom work from Zapco. It's nice that they would entertain customers in such fashion. That's what, ~$1400 worth of signal processors new?

The vacant spot is confusing, was there a second fader there?

No, no fader in the square hole. Unsure of what that is for. Weird setup. 3 AEX crossovers, 1 PX eq, 1 AFI Fader. Still missing one crossover for it. There is a set on Ebay right now, but he is asking way too much for them. How about the US Amps serial #6 ? Any idea Tim? Anyone? Also, does anyone know if Kicker and US Amps have a production deal at one time?

If it were built for Kicker, would it have the US Amps logo?

Any identification on the PCB? It's definitely an early model.

[tomtomjr]

Here is a closeup of the board where it says " OK DE Sept-1990 #6 " . (click on thumbnail for larger view) --- ALSO on the board is a US AMPS logo. Not much else for identification. No model number on the board. Any idea of what year US Amps started building amps? I worked for someone selling them in 92-94.

Actually what you have is a home-grown amp from my state of Florida.
I've sold and used many of these amps.

IT IS CALLED A US AMP KA-250 2 X 125 WATTS @ 4 ohms

At the time of production there was only one other model available that being a KA-50.'

Both amps were stable into one ohm and came hard-wired with STREET-WIRES power and ground wires.

Very good amps even by todays standards.A little inefficient because of the bipolar SMP. Standard TIP 35, TIP 36 outputs.

I can say this though when this amp was in production.Most of your Kicker Dealers sold Linear Power amps. They actual relationship was between Kicker and Linear Power,some of the reps were related to the owners. Jack M. (US Amps owner) came around pushing this little amp that could burn down trees (KA-50 and KA-250) and with the high retail prices of Linear Power,Orion,PPI,Autotek,Rockford,Hifonics, ects
US AMPS found a niche. And so in Florida where Kicker ruled. If anything US AMP was tring to infring on Kicker market share,and Kicker pushed back. I remember being threatened by my Kicker and Linear Power Rep (John Snyde) that if I didnt stop selling US AMPS I would lose Kicker ,Linear Power and VSE (the best car alarm company ever).The KA-250 whoop-*** and took names and the powers that be hated it but could'nt stop it. US AMPS was close very quick shippment,they were friendly,would modify,customize and warranty anything for you.you name it. If you stop by the warehouse you could place a order and get a tour of the factory (from the circiut board design room, to the assembly line) absolutley no part of the process was off limits.So I like other dealers told Kicker and Linear Power to eat-a-dick and they did.Then they came right back. MMats eventually saw the success of all the drama and jump into the ring with their own relationship with SEAS speakers.

I can hear Eidath and Arthie Bunker in my ear right now singing "Those were the good-ole days"
