The Radford is available again! As a student the owner bought it from Encel Stereo, possibly the last STA 25 series 3 to be sold in Australia. Now a successful medical man he is willing to let go of what used to be his pride and joy. I still have to get it for a reasonable price, I hope to sell it for $2500.
Conservative rating of 25w per channel from EL34 output tubes and EF68 with ECF82 driver tubes. This amp can be differentiated form the similar STA 15 by its manual bias adjustment.
See pictures earlier in the blog, just type “Radford” in the search menu.
