? Known problems:
1. 5.9v on 4.75v.min - 5.25v.max heater.
2. T/R relay hotswitches with modern transceivers.
3. No step-start to prevent eventual spot-welding the ON/OFF sw.
contacts.
4. Marginal VHF-stability -- i.e., tends to have parasites. (needs lower
Q VHF suppressor)
5. Does not have a kick-butt anode supply.
6. Larger diameter conductors needed in tank L for high bands.
