Customer Crossover Upgrade

After seeing our Crossover Upgrade video on Youtube a customer was inspired to do his own modifications. Instead of replacing all the components, he decided to only replace the components that the signal travelled through to get to the speakers.

"They sound pretty good: engaging, natural, musical. This is quite surprising, especially considering that the 2A3's being used are only the basic Psvane "Hi-Fi" grade, and also that the interstage & output transformers are only Hammonds, which aren't the most...

After an easy 2hrs 30mins drive we parked up at the Caboot Circus Car Park as we would normally. The car park is just over the road from the Marriot and close to Wogan...

One more than last year so the show is definitely...
