Testing Pseudo Capacitors

it turns out you can cook a lot of capacities out of bipolar triode

a descending list :: (also on the 1-st fig. below)
  • connect E2E2C2C using bases as outputs or (equals) tie E&C together and merge B-s
  • connect E2E & C2C using bases as outputs
  • connect E2C & C2E using bases as outputs
  • tie CB-s together and use as outputs merge by E-s
  • tie EB-s together and use as outputs merge by C-s
(PS! -- the shown voltage tuning takes up to about a second to settle !!!)

+ a simple osc. test ::
