Big amp is in storage so I took my Ampmaker SE5A to 1st rehearsal of new band on Sunday.
I was pleasantly surprised that it MORE than kept up with acoustic, piano, bass & drums.
So I got to thinking that I might even be able to gig small venues with it.
I decided to mod it to take a 6L6 instead of an EL84 in the hope of achieving a bit more headroom, so I ordered an octal socket and:
- hooked it up to green heater supply,
- shared the signal stuff and B+ with the existing nonal socket
- connected 1 & 8 to ground via the new looking 47uf cap and the 470r resistor (yellow lead that goes under the turret board).
It works with the 6L6 tube in (and the EL84 removed) but at a VASTLY reduced volume.
Can anyone spot what I might have done wrong?
