Pete Townshend

According to thewho.net website, Townshend used ARP 2600 synth for "Relay".

According to thewho.net, Pete used Wurlitzer 200A back in 1970.

According to thewho.net, this synthesizer was used on "Won't Get Fooled Again", and it was called "The Putney".

In this 1969 photo of his Twickenham home studio, a Vox Continental organ is visible to the left. A full studio gear breakdown can be found here.

Used during the composition of Who Are You, as mentioned by producer Jon Astley in this Sound on Sound "Classic Tracks" interview about the song "Who Are You".

"Pete would come in with a new song, which would serve as the backing track for The Who to perform on, and John [Entwistle] would do the same," says Astley. "Pete had a Polymoog that was programmed to play his backing tracks, and then the other guys would overdub their parts."

In Pete's studio, there is EMS DK1 visible. This keyboard is used with EMS VCS3.

Pete, on the organ sound for Won’t Get Fooled Again and Baba O’Riley: “I used gated Lowrey organ via EMS VCS3 gated filter. No sequencer. I got my ARP 2500 system (huge) just after I’d recorded the first few demos for Who’s Next. Baba O’Riley was a cheat. I couldn’t get the sequencers and mix-sequencers on the ARP under my fingers fast enough so I emulated sequencing and tape delays using the Marimba Arpeggiator effect on my Lowrey Berkshire.” https://www.thewho.net/whotabs/gear/guitar/lowrey.html
