If you adjust those inductors in the band select oscillators be very careful. It is easy to wear out the threads in the slugs and/or the coil forms the slugs screw in. It is also easy break the adjus

You can choose from various bayonet base miniature bulbs. If you want longevity go for higher voltage rated bulbs which will draw less current and glow on the red or amber side rather than bright whi

The exact capacitance rating is not important because when you use it, it is in parallel with the variable capacitor inside the 238. Of course it would not make much sense to use a real small capacit

And when you do need it you may need more than 1000 pFd. That is the reason it is on the outside of the box. It makes it easy to add whatever is needed. N6KB _________________________________________

Regarding 9 MHz Filters, Ten-Tec 9 MHz IF filters are mostly (maybe not all) NOT centered on 9 MHz. They have bandpasses of various widths covering a frequency range centered a kilohertz or so above

Plate current is not as great a concern as grid current. Excessive grid current can damage the tubes quickly. The power supply is probably not capable of supplying enough plate current to damage the
