We pass this on FYI. We have no direct personal experience of this service and no commercial relationship.
Our full service and Modification includes:
Safety check, drill and fit a HT fuse* and a fused/switched IEC block for safety. We now fit a dual IEC outlet in place of the obsolete 2-pin sockets. Perform fault diagnosis. Replace all the out of tolerance and physically damaged resistors with modern high tolerance types. Replace the full set of small signal electrolytics and dual smoothing blocks. Replace the full set of paper couplers and decouplers with HV polypropylene capacitors. Check valve biasing and recommend what valves, if any, need replacing. Faulty valves will be replaced at cost if requested. Full performance check and adjustment. 24 hour soak test/retest.
