Quad II full service and socket upgrade includes: • Fault diagnosis: during this period, if the choke,transformers or valves measure faulty, we will contact you and provide a replacement quotation. • The wiring loom and tag board are dismantled and the chassis is cut-out and drilled to accept a switched fused mains IEC block, and new loudspeaker barrels. • The Paignton 6 way socket can either left in place, if you intend to use a Quad 22 control unit, or have it removed and blanked off. The small blanking plate will contain a phono input socket. You will then be able to run the Quad II from any pre-amplifier/control unit. State your preference when you fill in your service request form. • Replacement of  cathode bypass and dual can smoothing capacitors. The white capacitors shown in the under-chassis view (see further details) are high performance, 16uF 600V polypropylene foil types and not electrolytics. The low ESR and longevity is superior to electrolytics. These will be fitted as standard with this service. If you prefer the original can type capacitor we can fit a dual 16uF 500V electrolytic inside the original can. • Replacement of signal coupling capacitors with high quality polypropylene types with copper foil screening. • Full complement of resistors replaced with High stability, low noise, high tolerance metal film types. • Full performance test and adjustment. • Finally after a listening test we carry out a 48 hour soak test followed by an electrical safety test PAT*. NOTE 1: Our standard price does not include replacement of faulty valves, chokes or transformers. We can add valves at cost.  NOTE 2: It is highly recommended that you send your Quad 22 and Quad II together so they can be properly electrically tested.  An unmodified Quad II used as a standalone amplifier is potentially lethal without correct earthing. The earthing is normally  completed through the combined Quad 22 mains connector and umbilical cable.  If you want to use your Quad II as a standalone amplifier, please see details of our Quad 2 connector upgrade Q2FSCU option.
