6DW5 vs. 6BQ5/EL84
Why is it that the 6DW5 is not used any longer in PP audio amplifiers.
A pair can output 30 watts vs 17 watts for a pair of 6BQ5 /EL84. The price of the 6DW5 is a third of the 6BQ5. I remember adjusting the different bias of my father's BOGEN DB230 40 years ago. A 7199 drove a pair of 6DW5. -- Alejandro Lieber LU1FCR Rosario Argentina Real-Time F2-Layer Critical Frequency Map foF2: http://1fcr.com.ar |
