[sdiy] Philichorda Organs

[Peter Blackett]

Hi,
just to clarify things, the early Philichorda Organs [ not the Gm751 ] 
used valve oscilators [ ecc82 ? ] and neon dividers. and were 
manufactured as far as I know from around 1961
they sound better than the later Organs as the waveforms from the 
dividers were slightly different.
key contacts were specially made so that the attack of the sound was 
slower than using standard gold contacts such as the Vox Continental.
there was a separate valve amp unit with built in Stereo reverb . [ that 
fitted underneath on the stand ]
later models used a transistorised amp built in with mono reverb that 
didn't sound quite as good.
but the two Organs do look similar to each other
there was also later on a two manual transistor / ic version with more 
voices available
regards Peter
