If they blow you just lose a couple of expendable 3055’s (and a Cheap BD139/140 pair) and not the speaker. Cap coupled speaker is probably a good idea when using 3055’s of unknown origin above their 60V rating.A huge proponent of handiwork and … pluk boekel Born in 1965, Katherine Gray attended the Rhode Island School of Design and the Ontario College of Art, in Toronto, Canada.Collector–Emitter Saturation Voltage - VCE (sat)= 1.1 Vdc (Max) … DC Current Gain - hFE= 20 – 70 IC= 4 Adc 2.
