Re: Tremoverb Hell

With HV everywhere, especially on the cathode, your return is not making it to ground. Check resistance from.cathode to negative HV filter cap. Then find where the connection is missing

Re: Weird Tube Preamp "Gain Recharge" Problem

Good points R.J. On all my probes I tape down the switch to keep that from happening. I've never needed a 1:1 measurement, and i like the reduced loading of the imcreased resistance. For the Rigol, and any scope in general, I'd recommend additional attenuation 100:1, or an added 10:1 before the prob...

Re: AI meets tube amp building, a happy story...

Just two screws to mount the plate? Looks like the toggle switch is in the way on the one and the stack on the other. Must be the photo angle.
Looks like a copper finish to help with heat dissipation?

Re: AI meets tube amp building, a happy story...

With no hand tools or metal, that's good for a one off. With a sheet of metal and basic hand tools, this is a 90 minute job start to finished plate installed. No delay and less than $4 of metal. $20 of metal on hand allows for fabrication of custom covers, straps, braces or supports to keep the buil...

Re: Weird Tube Preamp "Gain Recharge" Problem

Most Rigol scopes have eight vertical divisions. Set the baseline at the bottom and you have an 800V range of potential display.

Looks like a potentially great tool for complicated issues, but for this i use a machinist rule and hand tools.

Re: Weird Tube Preamp "Gain Recharge" Problem

Looking at the board I'd recommend touching up several of those joints. A handful look dry a few of the plate resistors and a 4K7 look like they need some solder.

Re: My oldest has decided not to go to college.

There's good money to be made in the trades. Trade schools are cheap, relative.to University.
Look at what plumbers earn, or welders. Just ask her to have a plan to convert an interest into an income. And most of all keep her off of Onlyfans.

Re: What transformer trickery is this? (RG?)

The anodes looked clean individually earlier in the video, so replacing the quad might not show anything.
I'd say it's being overdriven with an impedance mismatch on the OT primary.

ON-ON-ON Switch

Greetings fellow solderslingers, I have been using the 7211 series miniature switches for channel switching to get each channel or both. Does anyone know of a similar functioning switch in a larger case style? The plethora of connections and equalizing resistors makes soldering these up a brutal tas...
