The making of Frank's Sister

Post by Nils »

This will be the tread of one of my amp Projects. And i have called her Frank's Sister. Hopefully this will be a detailed worklog for this amp :)

The beginning :)

Correct length.

And here with Boards inn for mockup :)

This is how far i have come now, i have forgot to take pics of the drilling. Next step is to figure out how to do the wiring and endplates, and some other small issues :)

Thanks for sharing looks like fun. How do you tap the holes for the transistors that do not go through the sink? Just drill a hole and use a harder-metal screw to cut the threads and seat it itself?

Where in the world did you find a raw heat sink that long? Did you have it machined yourself?

This is the start of something VERY cool!!

Very cool!

What are the amps you are building this out of?
Being loud without good sound quality is pointless, but having good sound quality without being loud is also pointless.

My question and thoughts exactly. This is a very cool project. Il bet you can replace the power and ground connector on the end board with 4 gauge ones and then run 8 gauge wires to each board. Also, I would have left more room on the preside to allow for wiring up the individual gains, RCAs and other eq controls. May e would have even set the end plates an inch in to make the connectors hidden.
A few of these and a few of those.

Thanks for feedback, funny that no one have mentioned the pink dotted amp in the middle :)

@todd217: That is the plan to have all conections on one side, it will be a tight fit, i will try to get close to "original" look as possible.

@ttocs: i have drilled out the holes first and tapped them out :)

@zztunnell: well i have got them made for me, they are 96% similar to the original heatsink, have a couple of lengths of 4 meters :) you can also take a look at this link: http://www.phoenixphorum.com/viewtopic.php?f=3&t=18640

@Kirghiz: there will be 3 MS275 boards :)

@vwdude: when it comes to wiring i haven't decided yet, maybe gold bars maybe wire, i also have some issues regarding to bass eq (wich i wil newer use) and gain how to make it look nice and original :)
A lot of thinking :)

This amp will be a "test rabbit" as we say in Norway, i have 3 more amps to "build" that are bigger than this one. This is the amp that i can make mistakes on, the tre others i can't :)

I'll try to ceep this updated :)

when the hole doesn't go through the sink, how do you tapp them?

With what is called a bottom tap. It is square or blunt on the end and made just for tapping such a hole.

You use a bottom tap as groundpounder says, there are different taps for different jobs :) the tap i used isn't actually a bottom tap, but the closest you get, as you can see on the pic it has a "cone" like the drillbit, when you have drilled a hole it is much easier to feel when you hit bottom, this tap has treads all the way down :) sorry that i missunderstand Your question :)

In the name of saving space on the end how about a six over six terminal for the speaker connections like they used on the TI900.7?

I will check this out, but I will try to keep this as "original MS look" as possible :) and Eric, I know I need your experience and knowledge about a couple of issues on this project :)

I would use both ends for terminals rather than try and squeeze them all on one side, every LE amp is like that anyway.. maybe power/remote on one end and speaker/rca on the other.

As soon as somebody comes up with an oldschool amp project all the blokes come crawling out of their hideouts. :)

Great project! Keep us posted. Hopefully you´re using metric screws... :lol:

I still frequent these forums on a regular basis, I just don't have anything to show right now but fear not I have ideas brewing for the Skoda!!

by the way, what's with the "metric" business? MS amps had imperial screws didn't they?

I Think i have to try out a couple of different layout's the internal wiring have to look nice also. Thanks for input :)

Thanks Joerg, and of course there is metric here :) on this project there will be a mix I think, but on the other three I think I will do imperial...
