Radford TT100

Another really interesting amp has arrived needing a lot of tender loving care. The Radford TT100 is a hybrid solid state /valve amp. This one has been butchered over the years. While some components have been upgraded new components are held in place with Blue Tack, and others have been installed with no insulation so any movement or shock could potentially cause a major short circuit. Not the way I’d do any upgrades with 600v floating around inside! Thankfully all the transformers and chokes are in good order and having made the amplifier safe, it even made music on power up. Now for some restoration work to make this an everyday amp with decent sound quality and a lot of slam and dynamics!

These Unison Research pre and power amps are currently in the workshop for servicing. The power amp is the hybrid valve /solid state model. Repairs included the input selector and a choke for correct earthing and hum.
