I replaced all the caps on an old tube set aaaai was working on and got it to work great with the exception when tuneing on the low end of the dial I loose all signal pleanty of volume no stations, any suggestions.

What make/model of set is it?

Check for a bent gangs on the tuner. Osc. or Ant. section. Common to find touching gangs because this is the most exposed area of gangs closed.

Check your alignment on the 560kc end of the dial, usually there is a padder or adjustments for that frequency in the instructions.

And I say again, check your local oscillator with another radio. It is not likely, but it may be stopping at the low end of the band. Getting noise, however, makes this unlikely, but I am a b it nutty about this because if I had done it once, I could have saved myself a days work trying to find a RF amp problem, when I actually had an oddball intermittent oscillator.

the radio is a Westinghouse WR 332 as best I can tell.

Does the reception get worse the closer that you get to the low end of the dial, or does it abruptly stop at one point?

Sudden stopping at one point on the dial is probably caused by the tuning cap plates shorting out, due to mechanical damage (a bent or nicked plate) or metal trash (fragments from the rotor shaft ball bearings, etc.) lodging between the plates.

A gradual loss of signal as you move to the low end, however, could be caused by an inadequate antenna. If the set aligns OK with a sig gen at 600 Khz, but still won't pick up over-the-air signals at the low end, my guess would be that you need a better antenna, or something about the building that you are in is attentuating the longer-wavelength signals (for instance, a metal roof, metal siding, or steel-beam construction).

The signal stops usually at one place and does nothing all the way to 550 I paid real close attention to the alignment of the plates and cannot see them touching.

For each section of the tuning capacitor, connect an ohmmeter to the stator and rotor and move the cap shaft from fully open toward fully meshed. This will tell you for certain if the cap is shorting out- sometimes a visual inspection is inadequate.

Another thought- does the set work in the "dead area" of the tuning cap when switched to another band?
