quick question about an Admiral 20X12

Hello,

I just bought an Admiral bakelite table top tv model 20X12 and the on/off, volume knob is missing. In photos I've seen of this TV the three front knobs for the adjustments other than the channel changing knob all look the same. however when I try to temporarily put one of the other knobs onto the on/off shaft it wont fit because the shaft for the on/off knob does not stick out as far as the shafts for the other two adjustment knobs. Is it normal for this shaft to be shorter than the other two? if it is normal than I know it will be a headache to try to find a replacement knob for this tv... I haven't taken the chassis out of the cabinet yet so I just thought I'd ask incase anyone has this tv and could help me figure it out...

apparently the same chassis that is in my table top admiral 20X12 is also in the Admiral bakelite console tv model 20X122 and I think I've seen that some members have this tv so if someone could check their tv to see if all of the adjustment shafts are sticking the same length out or if it is like my tv I'd appreciate it..

Thanks,

Antonio
