NOTES |
This is the console version of the B18T. However you really don't get
an appreciation of just how small the set is until you look in the back
and note the relative size of one of the octal valves.
This is the first British console capable of running on DC mains as well
as the normal AC mains, although you needed to be at the top end of the
mains voltage range. The valve heaters are series connected and their voltages
add up to 230V and even then the sets can sometimes struggle to find enough
oomph to fully scan the little narrow angle 9-inch CRT.
Although
the Trader service sheet for this model gives a release date of September
1948, it can be seen from the advertisement opposite that it was released
a month later.

SERVICE DATA |
The chassis is basically that of the model B18T, the manual for which
can be downloaded below. |
CURRENT STATE |
The chassis, whilst very clean, looked to have been somewhat modified.
|
|
|
Nice short connections between the aerial
and the input transformer. Only two minor quibbles
1) Might work better if the transformer output was also connected!
2) It shouldn't be there in the first place! |
|
The coil probably once resided in the hole
which now provides an access path for some coax bodged onto the second
input coil. C.O. Stanley must be turning in his grave. |

|
Perhaps bypassing the HT rectifier with a couple of old diodes probably
seemed like a bit of a laugh after a few beers. |
|
Still, look on the bright side, this is one less cap worry about
failing ! |
I won't even mention the missing EB41's and the 7 pin miniature
valve base grafted onto one of the octal sockets. Not only had Barry
the Bodger been very busy but this was probably an heirloom, having
first been bodged by grandpa bodger. Thanks to Peter for sorting the
mess out.
Ouch, what a rough cabinet this was when it first arrived. Screw holes
in the front were probably left overs from a screen magnifier, the
dents, chipped veneer and worm holes merely from neglect. However,
Steve Ostler has done a jolly good job on the cabinet - it looks even
better than the above photo might suggest, as the photo is a bit of
a compromise in order to get a screen shot. |
The cabinet as it was. |
