Favorite 300B: Sophia vs KR

03-10-12: Pdreher
In talking to Brent @ VAC, I've found a way to get the sound of my old 30/30 out of my 70/70 Sig. by simply taking out a row (quad) of 300B's. In doing so, I essentially now have a 30/30 Signature in the body of a 70/70 Sig.

Hey, Paul, that's good to know! Another reason being that if a tube ever fails, it would therefore be safe to operate the amp with a row of tubes removed, while a replacement is being obtained.

To be sure I am understanding properly, what could be removed would be either the four 300B's that are closest to the rear of the amp, or the four 300B's that are closest to the front of the amp. Is that correct?

Very glad, also, that your Ulysses ultimately worked out well.

Best regards,

Al - I have the Signature version of the 70/70 with the enclosed chasis, so I'm not sure the non-signature version would be the same. I say this because I shared this tweak with Audiogoner "Waltersalas"... and he was unable to get his 70/70 mk III to work the way I was able to.

In my case, I removed all 4 output tubes closest to the front of the amp, leaving only the 4 output tubes closest to the rear of the amp. Brent said removing either the front or back row of 300B's would work.

Give it a try and let me know if it works for you.

It sounds so good this way, that I will be sticking with this 30/30 configuration as long as I have efficient speakers like the Daedalus.

Paul,
What are you actually hearing differently in the 30/30 format that you don`t with the 70/70?
Regards,

I'd love to have some WE300b's for my Cary 805C's but i'm not willing to spend $2400 for the pair. The new Psvane WE300b replicas have caught my attention. Have any of you guys/girls been able to listen to these new W.E. replicas? Or at least been able to find any reviews on them?

Thanks
