WAY too high failure rate.yikes. to each their own.i'm a stompbox guy, to me, i don't like ANYTHING on flying leads with a high gain circuit personally.and in repair, i've done more repairs on stuff with leads than mounted to the board.if it were tubes, where they're being subjected to mechanical stress and heat, i'd agree with ya, but imho board mounted is just as easy to fix and tends to mess up a lot less.but whatever works for ya is good by me

Quote from: Tassieviking on March 22, 2022, 11:17:16 AMI am a bit wary as well on any stress put on solder points, like pushing plugs in /out.If I use a jack on a PCB it will always be a stereo switching jack socket with 6 pins for the most strength.
Quote I made up draft 5 of the schematic, we will se how we go this time.pinkjimiphoton, I am not sure what you meant with the measurements on the Jack Sockets.I think you left a message on the DIYstompboxes forum that the measurements were to a pin and not the center of the socket.I am posting a picture with measurements, If you could write on the picture and return it I can get that fixed up as well.
QuoteI have the PCB nearly finished apart from moving the Jack Sockets to the final place.The strange footprint for the Tantalum caps is one I made up when I did the Sunn Beta board for myself.Its so I could use Electrolytics, Tantalum, WIMA Box caps where the 2uF electrolytics were on the original PCB.
QuoteOne more thing, the hole for the spacer between the heatsinks, do we want that in the same location as the original ?
QuoteI would need the measurements for that as well.The only tracks on the top of the PCB are on the TO-3 transistor, the original did not have any, they relied on the power going through the screws.There are also tracks on the fuse holders on the top, but they can be on the bottom, it's just the way I made the footprints.
QuoteYou can make it a one sided board if someone wants to etch one, just leave out the tracks between the screws on the TO-3's like Marshall did.
Quote from: Tassieviking on March 24, 2022, 11:51:23 AMSound like your back is the opposite to mine, my vertebrae between my shoulder blades have fused together to one solid lump of bone, and it tries to do that all over the place.
QuoteSoft connective tissue like ligaments and tendons start turning into bone, if my hole spine fuses and I fall it will snap.To be honest I hate taking oxy, but I use it practically every day when I go to bed.I never get a buzz from the oxy, not even when they fed me 32 tablets in 20 hours in hospital. If it is really needed for pain it does not give you a high, or maybe the pain was just so bad I didn't notice.
QuoteI have nearly finished the PCB now, just tidying up, then I will post it here for others to use if they want to.I will make a different one later a lot smaller, with the sockets off the PCB, and maybe add an effects loop and reverb on the PCB.
QuoteBut before I make this one smaller I will make one up for the Marshall 12 watt reverbwith an effects loop, I will combine all the 12 watt circuits I can find and add them all on one PCB, then just add the components you need for the one you want to build.I will also make the power amp a mix of the 12 watt and the 30 watt one, again just use the right components for what you want.
QuoteJimiphoton, you wouldn't have the measurements for the 12 watt amp would you ?I would be after the spacing of the pots and pots to jacks.ChersMichael
