Show too high resistance Is cause of Troit trouble ble in vacuum tube receiving elving sets seta rm l ni cloying grid condenser and leak it Is found in sonio cases that broadcast sig nils nals aro received clearly when the set Is placed jn in operation but suddenly easo ease alter after a short interval discon lie necking cling the plate battery and then reconnecting it causes the signals to be r resumed for another period and then lien wase bease abruptly as before tills this condl tion results from the use of a grid leak having too high a resistance thus allowing the accumulated charges to hoke choke tile the tube disconnecting tile the plate battery for a elme 1 bennu the charge to leak off and allows the set to junction function for a short interval until the charge builds op no and agal chokes tho the tube tho the remedy Is t draw a few i i pencil ller alln across the th grid condenser these lines should make good electrical contact at each end with the i posts of the condenser thus thu reducing uie ue resistance of the grid leak |
