My Marshall 1987

[Gonzo]

Hi there!

I'm relly into the DIY stuff and my latest idea is to build an amp.
I apollogize in advance for my "weird" english, I'm from Argentina :D

Well since I have experience soldering, can read electronic schematics and don't have 1700 dollars, do you think I can buil my own Marshall 1987?

Just for the record, i've never built an amp but I've found some good schematics and pictures of it.

There are plenty of kits available anywhere from $500 to over $1000.

I know, my question was more like, can I build a good sounding amp only by soldering properly the components as the schematic says so?

:p

ds on how skilled you are! If you have a brain, understand a bit of electronics, can check and recheck an amp circuit over and over making sure everything is right before firing it. If you're patient enough, so you don't rush your build and start trying to play before it's right. If you have the proper tools, i'd say yes, you've got a great chance of making a sharmall copy ! The hardest bit gonna be to find the proper components localy, or somewhere else, without paying too much for dem.

This site used to be good, but seems halfway down

THANKS A LOT!!!

I´m going for it!..and those diagrams will make it a lot easyer, you rock man :)

I think the only "tricky" to find components are the transformers and the valve sockets.

As far as the schematic, the only thing i dont understand is the "choke" what is that thing?:confused:

An inductor. To explain vaguely, it has more resistance to AC than DC, so hum doesn't go through (or slightly.)

Thanks Satamax

Other two things i got in mind are:

Do you have the circuit to add a pedal for switching between channels?

I there a simple way to have a master volume or do I need a thd or something like that?

I know it wont sound the same but if the change is not that bad i can live with it.
