No problem with this but it seems strange the voltage can be higher than the bias. And there is a tendency in time to the higher voltage swing capability (?)

I have seen (pictures about) not one srm1 mk2 with two 6-pins low bias sockets without the usual "pro only" and "normal" texts under them. So the more interesting is upgrading this variant to high bias but the reverse direction is interesting too. The question is the srm1 mk2 type name means the same high quality amp, class A with more than 350V swing etc. There was a lots of time between the variations. Would you be a bit more technical about this "bias change" ? What parts from where should I buy ?

| The Lambdas have a different sound character from the 003 (brighter, with less lower-mids). You'll either like it, or you won't. They're certainly more technically proficient than the 003 is. |

| There were several revisions of the SRM-1, and they do supposedly sound slightly different, but it's doubtful that the difference will be big enough to matter. Most of us here understand the polarizing voltage and and voltage swing are different things. |

| The concensus is that modifying something to support a different bias voltage is more trouble than it's worth. Making a forked cable like Spritzer's is a far easier approach. |

| Low bias certainly doesn't mean that there is less voltage swing. All low bias phones run just fine off my Blue Hawaii even at a fairly high volume level. I think you are talking about adding a 580v bias to the normal SRM-1 since the Mk2's all had a Pro socket. A +580v bias generator costs about 40$ in parts with an isolation transformer but you can skip that. If the amp already has a pro socket you can cut the 230v bias wire and solder it to the pro socket and vice versa. |
