- Page 29 SVETLANA TECHNICAL DATA 572B High-Mu Power Triode ™ he Svetlana 572B is a high-mu power triode intended for use in class AB, class B and class C RF and Audio amplifiers. The Svetlana 572B features a massive graphite anode for high peak overload capability and a high average plate dissipation of 160 Watts.

- Page 31 When fitted in the FL-2100, Fl-2100B, FL2100B and FL2100F linears they sometimes oscillate in the standby mode because, as Yaesu has confirmed, the cut-off bias is only slightly higher than cut-off. If the amplifier 'takes off' as an unloaded TPTG oscillator it can wreak havoc.
- Page 32 The Heathkit SB-200 which uses a similar circuit has 100V cut-off bias and is stable when fitted with the Svetlana 572B. This applies also to the new Yaesu FL-2100Z. The Svetlana 572B features a massive graphite anode for high peak overload capability and an average anode dissipation of 160W.

In the AB2 mode with 2.5kV EHT, it can produce over 600W PEP with low intermodulation distortion.
