  I will use them in place of 12AU7, change the heater, and see how...

  6cg7=6fq7 and they are almost eqaul to 12bh7, 6sn7, 12au7, 6c5, 6j7,

  and tri-wired 6j7,

  6922 = 6dj8.

  6CG7 also draws about double the heater current of 6922.

  Bigger problem: 6CG7 and 6922/6DJ8 are miniature 9-pin, 6SN7 are OCTAL base!

• If 6CG7 /6FQ7 = 6922......wait, there's the trouble. - Sector-7G 17:15:36 01/27/04 (1)

  The 6CG7 might be the same basing as the 6DJ8, but it is not the same electrically. 6DJ8 has about 3x the gm, 1.5x the gain and 1/2 the plate dissipation rating of the 6CG7. Just to scratch the surface.
  regards,
