Re: Joplin voltages (again)

Ooops!!!!
No sound!
I thought that this upgrade was so simple that even I could do it, but nooooo ;-)
So I guess I have done something wrong :-(
Here is what I have done (I think):
1. Took away C6 and C10 (470uF cathode caps)).
2. Took away R4 and R11 (1K) and instead made a link where they had been (cathode resistors).
3. Changed R9 and R14 from 200K to 10K (anode resistors).
4. Changed R1 and R2 from 110ohm to 470ohm (cathode resistors).
BUT, no sound just hum.
Can anyone give me some ideas?
