BF Champ

Post by jestaudio »

Just finished a BF Champ built to the ceriatone scheme, it worked first time but does,nt quite sound right, i think the first issue may be i,m using a 8 ohm cab with a 4 ohm OT, the OT is a Hammand unit so should handle a mismatch, the second being i subbed a 250k lin for a log, result is no real bass control, it made me wonder how much difference a lin pot could make :?:

The other issue is its a bit buzzy, the heaters no centre tap and i am using 2 100ohm resistors to earth via a 470 bypassed with a 22uf cap
