Threshold input sensitivity

Hi Musicman,

I am the original owner of one of these fine amps and love it.

The Input impedance is 50,000 ohms unbalanced, 600 ohms balanced.

If you need any other info let me know.

Happy listening,
Lou

Lngbruno: He needs the input sensitivity, not the input impedance. I've tried looking up info on this amp, but can't find that specific spec. If one of you two can tell me what years this unit was made, i can probably come up with the answer. My guess is probably about 1.5 volts, but that is strictly a guess. Sean

Hi Sean,

I purchased mine in 1990. I looked in the owner's manual and service manual and I didn't see "input sensitivity" but did see input impedance. I thought that was what he was refering to but obviously I was wrong. After your post I looked to see if there was a reference of the 1.5 volts and didn't see that printed anywhere. What else would I look for to determine the input sensitivity?? Even though I didn't start this post, I am now very interested in getting the answer.

Thanks,
Lou
