Here's a few photos of the finished amp. The chrome valve runners from Will at Radford Revival really complete the upgrades to the amp and come with new valve and input sockets.

The work done to the amp was the following:
-replace all electrolytic capacitors
-change cathode bypass capacitors to Elna Cerafine
-swap coupling capacitors for Mundorf ZNs
-change speaker binding posts for Audio Note silver plated
-add 20db attenuation to the input

The goal was to replace worn components and use some better-performing modern equivalents in key places while retaining the voicing of the original design. The penultimate photo below shows the new chrome valve runners alongside the original electrolytics dated 1964 and 1965.

I soak tested the amp for two days in my workshop using a variety of music and as a friend who popped round remarked the amp is 'stupidly good' and sounds just so musical with everything from Bach choral works to jazz from France Musique.

I'm sure Clive will be along shortly with his impressions!
