signal pin.
The original plug was unpolarised, but carried a red dot to
indictate the signal pin.
the problem now is, where can you get the plugs?
The book I mentioned suggests you can use a pair of 4mm banana plugs.
Have you tried them? The original plug was not screened or anything, so
the 4mm pluges should be OK.
Said machine is Stereo, 4 speed (including 15/16
ips [1]), can copy one
mono track to the other while mixing in the microphone input, and so on.
The speakers are somewhat Heath-Robinson. There's one in the case, used
for mono playback and the left stereo channel. And another in the lid.
For Stereo playback you uncoil a lead from a slot inside the lid and plug
it into the RH extension speaker socket. Then put the lid on the right
side of the machine, about 2m away. Of course you can also connect up a
pair of speakers or a stereo amplifer/speaker system...
Sounds like a nice machine. Vacuum-tube or transistorised?
Alas fully transistorised. The previous model (essentially a stereo
EL3542) had valves in the output stages. I would like to find that one,
I'd also like to find both of the 'Upright' models -- the EL3538
transistorised portable (2 track, mono, 1+7/8 ips) and the EL3514 (4
track, mono, 3+3/4 ips, mostly valved).
These are not particularly good quality machines -- my old Brennel
2-track mono machine will beat the Philips hands-down. But they're fun...
