Re: K731 puzzler, and a question on rectifiers
Chad,

Thanks for your reply. I thought that little speaker might have been a tweeter, but I wasn't sure.

You were right as to why Zenith did not use a 35W4 tube as a rectifier in this set. I did some figuring and found out that the entire filament string (seven tubes) totaled 109 volts as it was. Adding another 35-volt tube to the string would have brought the total to 144 volts, well above the standard line voltage.

Thanks again.
