The Geloso sockets are larger than the German DIN sockets, however even though I had the correct, obscure and hard to find Geloso to jack plug leads, these were electrically unreliable causing intermittent breaks and spurious noises. Rather than investing time repairing the Geloso connector leads I simply chose to fit jack sockets in my Echorec, which meant standard patch leads or musical instrument (guitar) leads could be used with the machine. Although this is a common restoration/upgrade for the Echorec, I should point out that any modification work will ultimately reduce the collectable value of the machine. That said, the modification is completely reversible as no cutting of metalwork is required – the Geloso sockets can be reinstalled and the machine restored back to its original state if desired.
To gain access to perform the modification work you’ll need to remove the Echorec from it’s carry case. The machine is secured by 4 large bolts underneath. To remove these you’ll have to turn the machine upside down. CAUTION: Before attempting this check that the drum is locked. The drum should be held in position by small locking screw located within the machine on the drum shaft. If the screw has been untightened at some point then the drum will fall out if the machine is turned upside down. You can check if the drum is locked by removing the plastic lid that cover the memory system and then gently lifting the drum upwards. If locked it will move a little, but you won’t be able to pull it out.
