[R-390] Re: [T-368_BC-610] T-3 removal question

[Joe Foley]

Unplug it!  pull the RF deck out about 4", short all
HV conductors to ground!

Reach to the rear, right-hand corner of the RF deck
and unplug the cannon connector there, DON'T drop it,
it may hit the 5R4's on the modulator deck.

When sliding the RF deck out of the cabinet don't tip
the front down too far as the 4-400 may catch the
front edge of the cabinet and break!!

When setting the RF deck down be sure to set it on
something FLAT as the vacuum variable caps are close
to the bottom and could be damaged.  They are
EXPENSIVE!!

Pull the MODULATOR deck out 4" and unplug TWO cannon
connectors in the left front, this will clear all
wiring on this deck.  Check the coaxes going to the
speech amp on the left side, mine always want to catch
on the cabinet.

The power supply deck comes out the same as the
modulator deck, becareful not to cause mechanical
shock to the plate transformer as they can leak oil
around the HV posts on the bottom.

That leaves only the blower and the antenna vacuum
relay in the cabinet to becareful of.

Use some caution not to let any of the chassis twist,
especially the RF deck, as this can cause brittle
things to crack.  Most notably the tank coil!

I can load mine into the BASAR/RV by myself but the
power supply deck is really too much to lift alone.

You will, very soon, learn why heavy casters are the
first order of business when bringing home a T-368!  A
sub-frame made of 3" channel iron is not overkill. 
The eight heavy handles on a T-368 are GOOD!
