Parallel 6sl7

Since I wished to use the 6SL7, I pondered other ways that I might use it. I finally decided to parallel both triode sections of the 6SL7 to lower the plate resistance, and to get a better noise figure. While experimenting with the plate curves for the 6SL7, I discovered that, with a plate voltage of 435V, I could easily get about 150V p-p. The.

The circuit is directly coupled to the 6SL7 SRPP input stage I have used it on a number of RF transmitters and modulators and I thought it was only fair if my hi-fi audio amplifier uses it too For applications that require improved performance, Figure 2 shows a single-ended-to-differential converter that has very high input impedance, 2-nA maximum input bias current, 60.
