Hafler amps on eBay -- High priced!

[dickwest]

Check out this eBay auction. A pair of Hafler amps sold for $225 and their shipping cost was $125. Wow, such high prices!

The SE-120 has sold for $100 to $180. Its shipping weight is only 20 pounds. FEDEX will take it coast to coast for less than $28. The combined cost for the two on eBay is $350 which is about $175 for each. This seller really got a bunch of bucks for his 2 amps and made out like a bandit on the shipping cost.

FWIW, the SE-120 is a very nice little amp. If you study the schematics, it is identical to the Hafler 9130, Pro1200, P-125 and DH-120. This is a refined and well designed circuit. I use 4 of them in my HT and like the sound very, very much.

I am too much of collector of Haflers and must get rid of a couple of them. For starters, I have a DH-120 to sell for $125. It is all checked out and is working great and has good cosmetics. Shipping weight is 20#. More about this later......

I've got a little fan noise in the right channel of my Hafler 500. What might be suspect in such a case?

I swapped it with my Adcom 545II. Wow, what a difference! They say all good amps sound about the same? Not in my system. Now I'm thinking about selling the Adcom!

Maybe try moving the wiring? Do any of the AC lines travel near input wiring?

I think those Hafler amps from the 80s are like Rodney Dangerfield. They don't get no respect. They remain one of the best bangs for the bucks.

There is only one fan and if it is making a noise you should hear it equally in both channels. The fan is AC driven. Perhaps you are getting some slight AC interference? I would check connections, touch up some old solder joints, and maybe think about replacing the old electrolytics on the PCBs.

Twice I have fixed similar amps by replacing the input cap in the circuit or resoldering its joints. It and the small film caps nearby should filter a lot of "junk" that creeps into the signal path. Are they securely soldered?

and I'm asking $50 shipping... That's a little more than the amp-weight warrants, but then I learned my packing skills from someone named DickW, and that sucker's gonna be double-boxed, and hyuge....

When I checked earlier, the bidding itself was at $50ish...

I'll look into your suggestions.
