For MRF477, looks like.

1998 board with a 1992 transistor on it.

I'd like it better if the caps and resistor were through-hole parts.

So I cant understand the french, L32 with the blue wire is going where?
There is a SMD 220 ohm resistor what is it doing? Is it a part that came off the main board and now on the new transistor add on board? Also there is a SMD transistor in there what is it?

This is what you meant by I hope Your french is good LOL.

Well that's a tough one. This is going to take some planning and a strategy.

You can start at the left and work your way to the right or vice versa. Or you could start in the middle and work your way out. You could do every other one and then the rest........

Just tell them to surprise you while you think about your plan of attack. Haha!

 

[Shadetree Mechanic]

So which one did you try first?

 

[kopcicle]

Zwick'l Lager - franconian-style unfiltered lager 5.9% abv
Zwick'l bier (also, kellerbier) is brewed like any German lager but without the flavor and aroma-stripping effects that can result from aggressive filtering methods. Gravity alone clarifies this beer, so expect to see some haze. Crisp, clean maltiness is a real thing and it is achieved by pairing a traditionally lengthy 5 step mash with a 9 week aging (lagering) process. Add to this a generous amount of Hersbrucker and Mittelfruh hops from Hallertau, Germany and you have yourself delightfully round, 4-season amber lager.

Again, either of the MRF101 or MRF300 boards I'm developing will need it's own LPF.

I've dealt with this "family of sellers" several times on lesser items with good results.

would need of course the usual control and protection circuits from the same sellers or https://www.w6pql.com/parts_i_can_provide.htm

Here are a few things from my garage. Had Our first real snowfall yesterday so got out on of my sleds, 2001 SRX700 also have a 1995 Vmax 4 800 thats been in storage since 2012 as they are going to be collectable. And for bikes I have a 2000 cbr 929rr and a 1996 RMX 250 with blue plate title and have a 1988 RZ350 project mixed with a 2008 Hyosung 250GT should be fun when finished.
