Roland SRE-555 Space Echo tape delay
via this auctionabertronix (RSS)
"Roland's professional tape delay system featuring advanced low noise circuitry and balanced in/outputs as well as stereo output. It combines four effects ; Chorus (analog circuitry similar to the roland dc 20/30) Echo (tape delay / 6 six modes ) Sound on sound (tape layering effect unique to the 501) Reverb (spring reverb tank) All effects can be used alone on mixed in any combination. In my opinion the sound is clean though the delay is still very much tape like in character. Where this equipment shines is in the ability to create and mix together very beautiful chorus/ delays/ reverbs so easily."
Oberheim OB-X 8-Voice Analogue Synth SN 800207
via this auction"Entire synth re-capped, from the power supply to the voice cards and everything in between. That means all the(over 80!) tired electrolyic and (unreliable) tantlum capacitors have been replaced with high quality new ones.
Every internal calibration pot(over 100!) has been replaced and upgraded(obeheim used cheap open types) with high spec 25 turn cemet types(more accurate tuning) or sealed single turn cemets pots(or carbon according to specs). This improves tuning and general adjustment stability on the OB-X massively!Entire keybed stripped, cleaned, rebushed(61 new pratt-reed bushes!), rebuilt and aligned. Makes the keybed play as new!
Many of the unreliable CMOS logic IC's and old Op-amps have been replaced and upgraded.
Modified to run a single more modern EPROM. This removes the need for the -5 and +12 power supplies, removing load from the supply and improving reliability
Every control pot stripped, cleaned and lubricated.
Every switch stripped, cleaned, lubricated and rebuilt.
Every molex connector(100's of solder connections) resoldered, to cure and protect against cold(broken) solder joints. (very common OB-X fault)
Power supply upgraded with beefier 4 amp bridge rectifiers(the originals are a known problem) and new +15/-15 regulators.
New Lithium coin cell type memory battery fitted with holder.(makes for very simple future replacement)"
