Gainclone heatsinks

[Peter Daniel]

Those heatsinks are back in stock and I can offer them at $18 USD a pc. The size is 7 x 2.5 x 1.4". They are pretty efficient for that amp. More pics here: http://www.diyaudio.com/forums/showthread.php?s=&threadid=9112&highlight=gainclone

Daaayyyamm! That comes to a little over $150 a foot for that extrusion! And these are from a surplus supplier?

P.S. I have an 8.5" length of this extrusion I'll sell you for $25 if you're interested.

Here is a place that sells it on the web:

It looks like the same thing.

But those are not exactly the same thing. They are missing copper tubing. The heatsink I'm offering is unique piece of hardware, which allows to build uniquely looking amp. Although mine are coming from a local place, as you see, the price I quoted was very close to what's available on a web. Of course, I'm paying slightly less, but for it to be worth my trouble this is what I have to ask. One could say, that surcharge is for the idea how to implement it.😉

If anyone is really interested in that design, I can also supply other custom chassis parts.😎

Yeah, the 632 extrusion is really nothing like that heatsink. It appears to be a closed-system passive heat exchanger, and is probably more efficient at removing heat from a small die than a similar length of that extrusion.

Hey Peter,

I was just at Active yesterday and spotted these, and was reminded of your amp. I was debating about buying a few, but most of the fins were a little bent out of shape. You could probably straighten them though.

Cheers,
RonS

p.s. ever bought Alps pots at Supremetronics? I picked up a Blue Velvet yesterday, still trying to figure out if it's real or a fake. I think it's real...

 

[Peter Daniel]

If you look at the fins they are all curved in one direction, but the new batch is pretty good shape. You can straighten them pretty easy too.

The blue Alps are definitely original. I've been buying them before. They used to have Black Beauty at the same price, but the log pots are not available anymore.

Thanks Peter. Yes, a few years ago I bought my Black Beauty from them, too bad they don't have them anymore 🙁 I also buy my RCA jacks there, the gold colour seems more Red than it used to be??

What about transistors? They now have 2SK170BL in stock, ($1.80! yikes). I've bought 2SK389 from them before, they look original but it's hard to tell. Do you trust them for Toshiba transistors? I need a few for my Pass Ono.

Cheers,
RonS

 

[Peter Daniel]

I think the parts should be fine. I usually get my 2sk389 from old japanese equipment. I'm expecting a big shipment of 2sk170 so I can sell you cheaper, if you need some. But you have to allow at least a week.

 

[transducer]

Peter, I'm definitely interested in your K170's, and I'm in no hurry at all. Can you let me know when and how much they will be? I'll have to see how many I need, don't have the Ono schematic with me. By the way, you are certain that your parts will be genuine? May I ask the source of the parts? I'm being very cautious these days because there is a lot of reports of fake parts/transistors etc.

Thanks again,
RonS

Oh, no. I didn't mean to imply that they were. Just thought they might be something you'd want. 'Course anyone else that wants it is more than welcome. And I actually have two but the other one's got about 14 taps in it. This one's virgin. 🙂

The heatsink I'm offering is unique piece of hardware, which allows to build uniquely looking amp.

Ah, ok. I thought the heat exchangers were a separate item that you'd added to the heatsinks. I thought what you were talking about was that extrusion and thought that there were four of them used to make up the amp.

I got thinking last night after I'd posted that the dimensions you gave seemed to be rather large compared to what I saw in the picture. Now I understand where the confusion came from.

My mistake.

Although mine are coming from a local place, as you see, the price I quoted was very close to what's available on a web. Of course, I'm paying slightly less, but for it to be worth my trouble this is what I have to ask. One could say, that surcharge is for the idea how to implement it.😉

Hey, you'll never get any flak from me for being a capitalist pig. 🙂

Anyway, the price makes more sense now that I see what's actually being priced.

'Other custom parts'?

If anyone is really interested in that design, I can also supply other custom chassis parts.

What 'other custom chassis parts'? The acrylic? The front and back panels? The knob? Prices?

Thanks.

Brad

 

[Peter Daniel]

Everything except knobs, I don't have too many of them (unless you are ready to pay $20😉). I can custom cut the acrylic parts and drill holes in front and rear panels. If interested contact me by e-mail.

 

[Peter Daniel]

I still have some of those heatsinks left, they would be $10/pc now.

 

[vicelord]

Hello i would like 2of this but i think the shiping will cost me a fortune what do yau think???

 

[Peter Daniel]

Airmail shipping would be $26, surface $12.
