Build This MoFo!

[ItsAllInMyHead]

^ Sure. Search for Mega328 on any of the major on-line sites. There are any number of variations. It's a component tester. Wonderful for quick and dirty checks.

thanks for the polish choke maker link!
still undecided for go for mofo or lufo?
lufo has a better damping factor?

I plan to build the normal version of MoFo but the heat sink BD120-20 is impossible to order from Sweden for a private customer. I could use a more efficient sink but I really like Mr Rothacher’s original look. Is there someone near Sweden who could help me ordering? Suggestions of other “cool” heatsinks?

Still 75 available from Farnell. Code 179955. At least in Italy.

It doesn’ matter how much I want it, Farnell in Sweden do not sell to private customers.

Improvise!
Find a different but still unusual heatsink that will fit.
Maybe something from an industrial PSU, like this, my ACA run at 1.5A at 28VDC. So more or less on a par with a MoFo at 2A.

Nice amp you got there! I will comb the net, hopefully interesting heatsinks appear.

That's a clever way to build a chassis! I like it!

Can a chinese silver version work?

 

[Zen Mod]

certainly

 

[sov]

Nice! Where can I get my hands one those beauties? C/W? Ah, the link.

Lots of copies on pinterest. Go by dimensions. Gives you C/W. Or Ali/E

I did get my heatsinks for the MoFo here. I think they are also available in Sweden.

Chassis are ode to SWTP Tiger .01…first amp I built!

 

[pinholer]

Neat idea!

I remember the Tiger 0.01. 0.01% THD. My first amps, as well. The rest of my system included a Dynaco PAT-4 preamp, Dynaco A-35 speakers, and Thorens 165 turntable. That was back in the mid 70s. Rocked my university dorm room. I still have the Tigers.
