signal generator advice

[Marioverkill]

Thanks to everybody !

You guys have given me what I need.My lack of experience on scopes and function generators had me going in all directions.I will look at a kit since building is the fun part.I have been searching ebay but didn't know what would have been a half decent deal.

Can anybody recommend good reading/tutorial for using scopes on tube circuits?

I built a Elenco function generator kit.

$30

They have the Rolls for $69

But you have to provide the 1.2-5v supply.

Tom you slightly misread that. You have to provide a 12V negative center power adapter. The 1.5V to 5V thing is if you want to sweep the frequency like you would on a synthesizer, using a control voltage (1.5V is lowest oscillations frequency, 5V is highest).

Geez, I have got to stop skim reading....

The MO2020 provides a sine and square wave output on two 1/4" jacks. The frequency range is variable from 20Hz to 24kHz, it accepts a 1.2 to 5 volt dc input on a 1/4" jack for external frequency control, and a 10 dB Output Pad is included to provide a -10 dB reference signal.

Thanks for the correction.

While you are waiting, you could download a copy of Visual Analyser, which as well as a lot of useful tools contains a really useful signal generator.

If you don't want to connect your computer directly to the amp, you can save the output as an mp3 file and transfer it to a cheap mp3 player. (Although I've never had a problem connecting the PC output to the amp input, I have killed a sound card connecting the amp to the PC input to use the oscilloscope / spectrum analyser features od Visual Analyser).

It's unbelievably good for a freely available program:

(No connection other than an impressed user!)
