Guess you need 4x to build a complete kit.


Also I did mail HS Marston for price quote, and they were more expensive than Fischer.


The version from Fischer is Custom build, and pre-drilled with a Fan.

Just mount those TO-3's :-)

Sammy,

if you're interested i can stop by at this (scroll all the way down) place when i'm in the neighborhood to ask if they still have some of the package deals left.
They've been lying on the shelf for quite some time, but when i picked some up all of them were still nicely factory wrapped, the Papst fans on my assemblies turned out 100%.
No ****-gin idea what the shipping cost to kick 'm over to your doorstep would amount to, of course.

BuTuWu:
the Quasi-Oz posted a cool idea on derating an AC-fan at one of his quasi-complementary amp threads.
An estimate can be calculated with the fan coil data and series LC formula, easiest would be to stick a low value foil cap (high voltage) in series with the coil and just see what's happening.
I just tried it with an 80mm Papst AC fan and it works like a charm, even a great way to get rid of Polyester crab caps.

This fan cooled heatsink that I'm trying to make a GB for should be as similar as the original.
If the majority think we should change any specs or someting please let me know.
Since they are making a "custom" heatsink we can make it as we want.


The goal here is:

To get a complete, pre-drilled heatsink with a 230v(120v) fan as the original were with 8xTO-3 in total.

And you will need one heatsink @ channel.

I wanted to get most work done, and just start mounting the components...


Price Quote from Fischer Elektronik

This model is 108mm long Heatsink + fan.
Special model for better cooling.


LA 1A 03 8 X TO 3 230V - With 8 x TO 3
H 108mm (Heatsink)

1 € 116,50 ea.
10 € 97,20 ea.
25 € 86,35 ea.
50 € 77,70 ea.

+ drawing costs / once € 40,00

Leadtime: about 6 – 7 weeks after receipt of order
