The tonewheel Hammond organ

 

The mighty tonewheel era Hammond organs manufactured from 1935 through to 1975 include
the famous B-3, C-3 and A-100 models, as well as the spinet series M-3, M-100 and L-100 models. Many are still out there and  still going strong, and that’s the way we like to keep it! 

 

We have the experience, equipment and parts to keep those tonewheels spinning. We are happy to set up and maintain your tonewheel Hammond organ for use at home, for live performance or for recording studio purposes. Servicing can include:

The Leslie tone cabinet

 

We also look after their partners in musical marriage, Leslie tone cabinets - the ‘whirling dervish
of sonic space’ - with service ranging from amplifier maintenance, motor overhaul, driver
re-alignment or replacement to full rebuilds. The Leslie valve-powered and later solid state tone cabinets are 50% of the magic you hear when a big old Hammond is cranked up live in the room - they deserve to be in top shape, mechanically and sonically. We can help with the following:

 

Mechanical service

Motor servicing or overhaul

Belts, pulleys, bearings

Drums, scrim cloths, horns, reflectors

 

Cabinet

Running repairs & re-inforcement of loose joints

Tube amplifiers

 

The ‘impossible to replicate’ valve amps of the 50s and 60s are our other specialty. Vintage Fenders - Tweed, Blonde, Brown, Blackface & Silverface era amps. Gibson, Supro, Magnatone, Valco and Gretsch amps - and not to forget some of the British and European amps - early Marshalls, Vox, Roost, Selmer and the rest. We also look after Australian and other antipodean amps such as Moody, Goldentone, RM, Maxim, Electravox, Jansen and other sweet sounding relics of the local valve-amp heyday. The TLC for your prized valve amp starts here: 

 

Power supply overhaul

Output valve check or replacement
