Get the 15H/75mA choke that Hammond offers and call it done.

I happened to look up from my vermicelli bowl at a little Vietnamese restaurant yesterday and caught it. I personally thought it sounded terrible, but different strokes I guess. Still pretty cool.

And as for ripple in the PS.... even with my low filtering I don't have any issues with hum. Perhaps consider lead dress or component placement?

Mark, the hum you hear before the tubes are operating is transformer coupling. It may be worse when using different output trannies as I found out the hard way when using a MM 4/8/16R Princeton OT that was a drop in sub. I actually measured around 130mV on the primary! It was so loud that even at fu...

Mark, I don't care for the hi/lo input setup and just use the #1 input. Sometimes I put a switch in #2 that disconnects the nf and adds a bypass cap taking it to a whole other level. This one has an old dead jack for #2. As for the layout, I cut and drill my own boards to save space and do things ju...

Okay fancy pants just kidding. They look identical.

That's so cool!

I love my Fluke 115.

The 5F1 is my favorite amp to build and I've never had any hum issues due to internal circuit wiring. The only hum I've had issues with is transformer coupling on those steel chassis. When I stop playing and mute the strings it sounds like the amp is off. And I personally wouldn't use shielded wire ...

This is distressing news as I used to order from Triode

Well I just changed the settings in the notifications pull down menu so we'll see what happens. Thanks guys. Someone shoot me a PM lol

Nichicon.

Any chance we can get these again? Or do I need adjust the setting myself?

Not the first Dumble to use a round Accent knob that differs from the rest. #94 has that appointment.

Hmmm hazy pics a day after 4/20....

I love those brown drops and just used a couple in a brown 5F1 that I was reserving a 60s brown frame Jensen for. Sounds great. I just ran across Fleabay looking at caps and there are quite a few brown drops listed right now. Expensive, but I think I saw the values you're looking for. I also saw a ...
