K8060 Bias transistor

Hi

I am replacing transistors on a K8060 amp

Is the bias transistor T6 a BC547 or BC 547B (or even c?) ( difference in gain hFE (B = higher)

In the parts list T4 and T5 are shown BC 547B and BC557B

The Bias is T6 however is not in that list but shown elsewhere as a BC547

In the diagram T4 and T5 and T6 are shown as BC547 & 557without any denomination, type A,B or even C?

I have replaced T4 and T5 with B-types as per the parts list.

So following this inconsistency is T6 Bias a 547 A or B?

Thank you

If it is not specified, it is a ‘B’.
‘A’ is very rare and in case of a ‘C’ it is always specified.

Hi,

The ‘B’ is specified in the partslist but T6 isn’t even in there.

Thanks very much for the help

Cheers

T6 is the transistor which is not mounted on the board but against the heatsink.
If it is missing in the kit, please supply an address and we’ll mail a spare part.
