Guys,How do I use a multitester to determine if my tape outputs are actually outputting the voltage they are supposed to?
Plug the + lead into the output jack and ground the negative? Is there some minimum value I should see? It is an Eico HF-81.
Your help is appreciated. The reason for asking is I connected my Eico phono stage out to an amp without a phono stage. No sound was heard or rather at full volume on the amp, you could hear something barely audible.
Follow Ups:
Hi guys,A quick follow-up. Don't know what I am doing but I set my multitester at 200mv. Plugged the red lead into each tape out and grounded the black lead.
Readings with the amp turned on and no source playing. Left channel was -26. Right channel was -48. Have no clue what any of this means. Also checked resistance and of course had two very different values.
Can someone tell what any of this means... other than my tape out would appear to be messed up.
You're not going to be able to measure output without a known input. Use a test cd with sine waves, switch the pre to tape out (or monitor) and measure. It looks like you used a DC setting on your multimeter, you need to use an AC setting. Your tape out should more or less equal the output of the CD player.Have fun,
