TECHNICAL. USING SUEPLUS REIAYS
There are quite g. few surplus relays available but
getting the DC for their operation is soaetimes a problem.
One way of doing it is by placing them in series with a
power supply. The current required varies with the type of
relay but ^0 niao seem. s-acLequa-be for the snaller -types and
100 ma. for the larger, aerial switching -bype s. The DC pass-
ing through then should be reasonably filtered to prcvezit hum,
or'buzz, v/hichnver you prefer.
A typical in.st all at ion is shovm 'below. The values of
resistance shown were those -bhat happened- to be on hand,
lov/er values would probably be OEo Check that the coil volt-
age is not excGeded and"that the contacts are ad.equately
insulated- for the voltage broken,
I'L_B_. Do; not switch in. the centre-tap of the transformer if
the filter is of the choke inpu-fc variety. Use a separate
heater 'bransfornier and. switch in the prifflary of the plate
transformer
