I am considering upgrading/fixing my quad 405. One of the boards is so crusty with burnt carbon and the tracks on the PC board are lifting. Guess its either pensioning off time or rebuild. A year ago I replaced the transformer and power supply capacitors so I'd really like to fix it. The question is has anyone any experience of these modules? Are they any good? Are they reliable? and at over £200 are they good value?:confused::confused:
