Balancing Act Tube Rolling - Page 2

Yes it is a Brimar tube made by STC (Standard Telephone & Cables).STC started in 1883 as an agent for Western Electric

So am I right in saying that to use the Sophia or KR  PX-4 with the BA, all you have to do is change the voltage from 5V to 4V?

You also have a switch in the back.

XII I am using EAT 300B and a TS BGRP driver.

I thought the switch in the back controls whether the preamp outputs are RCA or XLR?

Are there any general statements that can be made about the sound of px4 v 300b?

The EAT 300B compared to the KR PX4 have better defined mids and smoother lower end.

Together with the TS BGRP they make the SR325is sound excellent.

switch + voltage when changing tubes, not that i have done that yet.

Anyone try the Shuguang Treasure 300b?

 

My Balancing act will be arriving today! I have loads of 6sn7 to roll: Ken-rad VT231, RCA VT-231, Sylvania 6sn7gtb, RCA 5692, Sophia 6sn7,  Shuguang Treasure cv-181z, Brimar cv1988....but not the Tung-sol round-plate...are they really that good?

Don't you get the Western Electric 300b with the amp? TSRP, are that good.

Actually, it turns out I only get JJ300b due to a misunderstanding (which I guess partially explains the low price).

XXII you got an excellent deal, if I known somebody was going to sell their BA so soon so low I would have waited for sure!

And yes the TS BGRP are that good!

Just make sure you get a nice, strong tube, you won't be sorry.
