    That is 30-0-30 VAC for a 25W amplifier. This checks with the parts list for a service manual available from Hifi Engine for the version using the TDA1514 where the schematic shows +/- 28Vdc supply rails. The datasheet for TDA1514A presumably an update shows a maximum supply rail voltage of +/-30Vdc.

    At 30 watts per channel into 8 oms, the Cambridge Audio A1 may not be the most powerful amplifier in the world but ideal for a starter budget system or for use in a secondary system in a small room. The Cambridge Audio A1 is probably best matched with a speakers who have a sensitivity in the region of 86-90db due to the power output.

    Hello so i bought a cambridge a1 mk1 (the original version) off someone and they said that the main board glass fuse blew and to change it and it would work. However after changing it the amp still doesn't turn on. None of the other fuses had blown, it was the T3.15A which blew which is the last...

    That was a great buy and it proves true that it can be cheaper to buy a used amp than a new transformer - if you have the skills to repair it economically. So, the OP could buy a stock transformer from Farnell etc. but at £34, they're rather expensive for a cheap import. Maybe there's there's...

    A transformer is the part that supplies power to our devices; be that an amp, streamer or CD player. A transformer consists of a pair of coils wound on an iron core. The AC in one coil produces a changing magnetic field. This changing magnetic field induces a voltage in the other coil of the transformer. There are two types of transformer ...

Converting a Cambridge Audio amp from 230v to 120v? | AVS ...

    I lived in England for a while, and bought a Cambridge Audio A1 Mk.2 integrated amplifier while I was there. I have been back in Canada for a few years, and the amp has been in storage all that time, because the back panel said it was rated for 220-240v only. I wanted to clear out my stuff, and while cleaning it, I decided to open it up.

    As I see it you need a 46 volt centre tapped trafo capable of 300 w cont. And a 230 v primary. , That means a RMS current in the secondary of 6 amps. Impedance etc are irrelevant in this context. The requirement in the auxiliary windings is a maximum current of 1 amp and a 30 volt centre tapped trafo will be overkill.

    Hello I have a old Cambridge audio A1 amp. There is a place in the amp for a Phono stage board but these are no longer made. There is enough room to fit one I have that connects via a wall transformer. It is 12v. Question Can I take the 12v required from the A1 PCB board? there are 5 pins in a row marked Gnd Gnd Gnd -V +V.
