Default Re: Quad 303 repairs.

Hi.

Note some of the later Quad test sheets show 2N3055 devices on the service sheet. ( Drawing No M12160 iss 1) I queried this in 1998 as the voltage ratings looked tight. I quote directly from the letter I received from QUAD service.

" The 2N3055 was a selected device. We now use the MJ15003 at £2.68 each plus VAT and postage."

No mention was made in the letter of any other component changes made for the device change and I can't recall any.
