5F10 build completed
« on: February 01, 2022, 01:57:42 pm »
Hi all.   I have had some parts sitting around and always wondered what a Fender 5F10 Harvard sounds like so in Dec I decided to build one. Not a clone but a tubes up model of the circuit. I had a Hammond aluminum chassis, a Classic Tone multi-voltage PT that I was originally going to use for a SE build, and that Hammond S-6 OT plus many of the small parts and tubes. Thanks to my friend Michael of Chelli Amplification in Durango I received an early Christmas present, the red board, some turrets and a 7 pin tube socket. So I got to building. Of course I made a post about the S-6 OT as I had found it was unsually center tapped. I found it to be unusable, and not very efficient. I had already drilled the chassis for it and made some stand up brackets, but I pulled it and bought a Hammond 1760E. So thats why the wires are not routed into the chassis in the usual manner.  Oh well it cost $50 more no biggie. The wire is from the Hammond S-6 and I really like that wire. I could have mounted the pots 180 out and the wiring would have been cleaner - live and learn. I think I would have rather used a wider and deeper chassis, but I had the chassis so I used it. Was trying to go cheap with this. The Hammond aluminum chassis are really kind of flimsy but easy to drill and they firm up some when you get the iron and board mounted.  I had wondered about building with them too. Now I kind of like them.


How does it sound?  It's a little monster that gets some really cool grinding distortion when turned up. And it is LOUD!! 


Edit.  I have to add the amp has some sweet glassy overdrive with cool sustain using singles turning up to around 7-8 and turning down the guitar vol..  From Strat straight into amp.

Cool!
I've always wanted to play through a Harvard - the amp of one of my guitar heroes.

Very nice! Seems you're on a roll.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Thanks guys -  I've been wrapping up some projects I've had in the works..for too long.  Now have to make the cabinets. Oh and I straighted up that dale resistor on the right 6V6 that probably got bumped wiring the impedance switch.

Looking good bud! Can’t wait to see the cabinets.

Are you doing combos or heads or maybe one of each?
It's never a dumb question if it prevents a dumb mistake.

They will both be heads.
