Hello everybody,

I am trying to find out what is a device called VR 100 PRESET which I found near a thermistor in a schematics of a transistor amplifier.
I am italian and I don't know what to ask to the electronics shop. They have no clue too. The symbol in the circuit is a resistance with a T crossing it.
Is it a variable resistor or something? Is that 100 the value in K?
Thank you in advance for your reply!
=)

Absolutely!
How much do you want to make a good working (and sounding!) PCB from that schematic converted to 200VAC 50Hz?

Hello,
this is the first time I write in this forum. I can boast being a newbie
in many fields, including but not limited to guitar amplification and electronics
so please forgive me if my posts are quite boring. But if you can, please
help me.

I have got the schematics for a solid state guitar amplificator but I don't
have the necessary skills to make the PCB, I have asked some friends of
mine for help but they have no time.
Also, the amp is american and I live in Italy, so I need to convert the
tension to 220VAC 50Hz.
I have asked in some usenet forums but many answers were like "buy one"
or "use this, use that instead of what you want" but really, I want that
amp because it is one of my favourite ever.
It's a Randall Century 200. Of course I will give the schematics to anyone
who would help me.
If someone can help me building a good working amp without frying my
guitar or cabinet, that would be great. I am asking here because I am
afraid I could ruin everything if I make it by myself.
Thank you for reading this message.
Bye!
