Default Another Bogen CHB 100 Conversion

"Hi to all"
I have CHB 100 that I would like to convert to a guitar amp for my grandson.
I have searched for quite a while and found a few ideas , I don't want to re-invent the wheel! I know many people have done it but know one has posted there final work.
Trying to replace the pre-amp with a pre-amp design from a Fender 5F6-A using the 12AY7 and the 12AX7. Leaving the 6C4 and the 4-7868 tubes. I have a schematic that a great guy helped me with, I would like to post it and have the Great people in this forum tell me if there is a chance it will work. I haven't done much to the amp but starting to replace all the electrolytics, no matter what I do they need it after about 40 years they must be tired!
If anyone is interested I can email or post the modded schematic its in a jpeg (1Meg) format not sure what is allowed in this forum.
Thank You for listening
