Another Update on model 87 restoration
#1

Hey Guys,

My tubes came in the mail today. I plugged them in and stared at the power switch knob for quite awhile mustering up the nerve to turn it on, not wanting any bad news. To my surprise it powered right up and after a few seconds I had music coming from my speaker.

All is not perfect, so I have a few more questions:

I'm having a problem with the volume..I have to play with the knobs to get the volume down to a comfortable listening level, it has enough volume to run you out of the room. I'm not sure I understand the controls completely. For any of you that are familiar with this model, there are 4 knobs. Going from left to right, I assume the first is the volume control. To the right of that, the upper control is the tuning control, directly under that is the on/off switch. To the far right, there is a device that looks like a mini variable capacitor, which affects volume, and has a detent if you turn it all the way counter clockwise. What is this control? The control all the way to the left doesnt seem to have any effect on volume.

Any help with this would be appreciated. I think I'm getting close.

Wendell
