Default Power Supply Voltage For 5881/6L6 Amp

Hi there,

The power transformer in my 10-year-old Arion Elektra tube amplifier has failed. No schematics came with the amp and there are no discernable markings on the transformer.

Tubes are 4x5881(6L6), 2x6SN7, 2x5814A(12AU7/ECC82). The brochure described it as an 18 Watt pure class A triode coupled pentode design.

Does anybody have any idea what the likely power supply voltage would be for such a design? (I'm guessing 350Vdc off a 250Vac secondary but that's just a raw guess.)

Arion also sold the Adonis kit amplifier, which had the same tubes and may well have had a similar circuit design. I have attached rough schematics for this kit amp that I got from an enthusiast via the 'audioasylum' web site in case it can give you useful clues to the design of my Elektra.

Many thanks guys, Simon in Edinburgh

no I think you will likely need more, is it a ss rectifier.

factor on 450 volt on the anodes

lose 10 volts in the choke if there is one and output tx,

so you are looking at perhaps 350-0-350 with a hefty current, 200 ma, and 6.3 volt heaters, lots of them 6Amps plus, try hammond or silk.
