In Reply to: 300b with Tangos need help posted by timothygurney on November 6, 2009 at 09:11:32:
Tim, hi. Old Tango interstages. I like them. In a SET with 6900 driving NC-15 to Type 50 (or 300B) to Tango XE-60-5SNF. Also 1/2 6SN7 to drive NC-16 to Type 45 to MQ DS-050. Beyond beautiful. Transcendent. A musical jewel. Here are the NC-15 specs. Zp is 10K Ohms. Minus 2 dB down points are 35Hz to 35KHz (rp=10K Ib=7mA). Max DC 15 mA. 50H (Ib=5mA)
rp=7~12K. The XE-20-600S is not intended for 300B. Zp=600 Ohms. It is intended for 6C33C. DC max = 320 mA. -2db 4V rp=Zp 30Hz-100KHz. For 300B you would want 3.5K although I prefer 5K.
