Hi all, Finally getting around to (slowly) building my next amp. I've wanted a 5F2A-type amp for quite a while, but I hate working in those tight Tweed-style chassis - so I ordered up a Zach Hunter 6G2 chassis on eBay and will make that work. Unfortunately (and I didn't notice 'til after I bought it), his 6G2 chassis is drilled for a Deluxe-sized PT & OT, so I will have to do a little drilling to make my PT & OT fit. Turns out this has come up before. Chassis1 by mabinogeon posted Jan 2, 2020 at 6:56 AM On the front panel I added an SPDT switch and another pot to fill the extra holes. The switch will flip between two different value tone caps, and the pot will be a presence control. The extra holes in the back will have a switch to flip between the two different pairs of PT HV secondary windings (ClassicTone 40-18027), and another SPDT switch, this one to switch between two different value cathode bypass caps (25µF and 1µF) on V1A. (Maybe. I may just use an SPST to switch the 25µF cap in and out of the circuit.) In the past, I have built amps point-to-point and on Fender-style eyelet boards. I wanted to give turrets a shot, so I picked up a few pre-drilled boards. I may drill my own in the future, but I have to say I absolutely love the turrets and will never go back to eyelet boards. Board1 by mabinogeon posted Jan 2, 2020 at 6:56 AM This is my first attempt at building a turret board, and I've already found a few things I'd do differently next time. I really don't like how the signal caps are on top of the plate resistors. I left an 1/8" air gap, just in case, but in the future I will space out those turrets an extra hole or two. Probably wouldn't be an issue if I used M150s, but those Jupiter caps are fairly large. I probably could have scrunched everything up a little tighter for the sake of neatness - but the chassis is plenty big and the extra space between components is nice for my clumsy fingers. The extra turret on the bottom left is for the PT heater center tap. I thought it'd be handy to have a spare hole to drop it in once the board is installed in the chassis. I haven't decided on the cab yet. I will build it, but I'm not sure out of what yet. For the speaker, I have a Jupiter 12SC in the mail. Will try to remember to update this thread as I make progress!
