Screw Fender. I like Hoffman-style!
Are those 716's
Those are not as fat as a 715

I leave a little breathing room between most of the parts on my boards also

I started my own Princeton Reverb build with a Hoffman Turret board

I'm posting pics as the build proceeds here

I also have a thread on my forum here about the build.

This is a remarkably great looking build! That layout board makes sense to me.

With respect, 10thtx

I forgot to post back after I finished this project
I finished the PR build and all the documentation.

One of my forum members bought the finished chassis and I did a few video clips of the amp before I shipped it.

Here's the build page with links to video clips

Here's the Schematic and layout diagrams
http://el34world.com/Hoffman/files/Hoff ... Reverb.pdf

It was a fun project
I hope to be able to do more these builds with some of the other Hoffman turret boards

Super pretty, Doug! Love it.

What chassis are you using? I hate to see Leo's ancient design getting in the way of good lead dress--for heaven's sake, can't we move the fuse and power switch closer to the power cord?

You videos are great, but have a nasty distortion. That Satriani-looking Ibanez is pretty flexible, sonically.

Keep up the awesome work.

Thanks, the camera microphones are not the best but they get the job done
Of course it's much different in the room than what the camera records.
The camera mics are thinner sounding and more trebly

It's the Mojo Princeton Reverb chassis that I stock on this page
http://hoffmanamps.com/MyStore/catalog/parts6.htm

I sell the chasiss and faceplates lower then the source does :)

Yeah, I love my Ibanez Satriani 24 fret guitar
I play such a wide range range of music I need something that can do clean to scream and that white guitar does it just fine for me
I sold my Strats after getting that guitar. I just did not play them anymore
