All, I've got a generic Philco radio question. I've worked on some radios that had schematics with warnings not to turn on the radio without the speaker attached. I'm now working on a 40-165 and I'm wondering if I can power it up safely without the speaker. Since the filter caps and many film caps had been replaced I thought I'd power it up but I only get a ticking sound. I've got the speaker installed in the cabinet and the radio is way too big to move and it's a pain to remove the speaker. I'm hoping it's safe to power up on my bench without the speaker. Also, are tube pin resistance and voltage tables available for Philco's? I hate to split up threads, the radio I'm working on is here Philco Radiobar Zephyr .
Thanks,
Keith
