Bypass caps for the Cornet= Additional gain???
« on: 10 Dec 2003, 03:58 pm »
If you put lets say a 100uf bypass cap on the cathode of the first two tubes that would increase the gain.  But what else would it do to the circuit?  I do not understand the riaa stuff very well.

Thanks in advance

Yes, you could increase the gain by bypassing the cathodes.  It also greatly changes the equivalent plate resistance of the tube (about a factor of 2 in this case).  The EQ will therefore be screwed up.  You'll need to change the EQ caps and resistances.

The cathodes were purposely left unbypassed for better sonics.  A simple design tradeoff - more gain or better sound.  

jh :)

Count my vote for BETTER SOUND!

IMHO one of the many design strengths of the Cornet is that there are NO CATHODE BYPASS CAPS.  


Another is that, at $99 for the board and about and a few more $$ for parts, it is darn near free!
