this is so cool....

would anyone be kind enough to give me advice on building an adaptor so that my four pin mk 1 suitcase can use its vibrato without the speaker?
or am i better off trying to find an original speaker?
the scematic says i need 25 volts, whereas people keep talking about 24 volts.
i know i need an adaptor and four diodes and a capacitor. that's all i know.
i promise it wont be your fault if your advice electricutes me.

If I were in your case I would ask Mrs. Google:
e.g.:

search for power supply and read something about it.
Basically your right. U need a voltage transformer, a rectifier (diodes), one or two Condensators and better would be a IC voltage regulators.
The link above is quite good. Writing advices in a forum is not the best way, cause I can't paint schematics here.
Sorry, but I think the link will help you out.
Good luck

thanks mark II
that's hard stuff on that web site. and i thought music was difficult.
but cause i'm so reluctant to pay someone to make my tremelo work, now i'm gonna have to learn it myself.

[jim]

wow i did it. i made the tremelo work and didn't blow anything up!

Well done jim.
That is what I like to do aswell. Find a MK2 preamp with vibrato for a reasonable price and replace my normal stage piano "preamp" with it.
But they are too seldom and therefor to expensive.
have fun playing it
best
