Great Can't wait for the next video. When using mondorf capacitors does it matter which direction the input signal enters considering it has a foil. Have you experiment with this, some say yes it has a direction some say no. I just noticed mine had one lead shorter than the other. Thanks again for another great video !!
I normally try to wire them with the signal going left to right with the writing on them facing me, but I screwed up and wired one of these backwards. I wasn't going to throw it away over that mistake. I've honestly not heard any difference but ideally you do want the outer foil going to the lower impedance.
Looks great ! Can't wait to know the sonic result. It's true that I never saw a pontentiometer at the output stage of a pre eamp. Anyway it's nice to experiment things.
Very cool design. Thanks for the link to the schematic and site. I’d love to try this design with octal sockets for 6SN7, 6SL7, etc. too. Looking forward to the deep dive vid. Have you ever experimented with a transformer volume control? Thanks for another great vid!
@@hyperion8008 That's really a different animal: it needs a TON of gain and is VERY susceptible to hum and noise. Would likely need DC heaters, more power supply filtration etc. Not going to happen with 1 tube like this pre-amp uses.
This has become a very high-quality device But. . . you can pimp this with a second tube. . . . if each channel has its own system. . . (this will reduce the crosstalk of the channels against each other).... Must be sounds great as it is! and thx for the vid!
Great video! Where do you source your hookup wire? Teflon or PVC? And where do you get your lead wire sleeves/coverings? Subscribing to your channel has really improved my diy construction skills. Keep up the good work!
Wow. Just checked out your web site. Glad I found you. Great stuff.
Welcome aboard!
Beautiful and intelligent lay out!
Ciao you are too good explain in simple words what may seem very complicated ... I follow you with passion a greeting from your fan from Venice Italy
Great video as always. Can't wait for the deep dive into the schematic on the next episode.
Can hardly wait to see how this amp turns out.
Very neat and clean layout.
Thank you!
I sure enjoy these videos. Thanks😊
great videos you are making , so educating
Cool stuff. I'm inspired! 👍
This cat does some nice work 😁👍
Very nice!!! Very informative!! Do you have a parts list? I’d like to make one. Thanks.
No, sorry. There might be one at www.cascadetubes.com/
@@SkunkieDesignsElectronics Thanks.
Nice work
Great job
Looks great, thank you
Great

Yesterday I saw an ad that advertised radio for sale one dollar volume stuck on high. Thought I can't turn that down

I guess it's no different to a pot on the input to a power amp?
I plan to cover this, if the amp has a volume control, you should leave this one out.
may i ask ? Is it needed a switch for the heating of the tubes? I am using in my diy el84 amp
No reason to IMHO.
Did you ever do a "deep dive into the schematic" hope you are feeling better,
yeah, I could look at revisiting this little preamp!

Not heard of transformer volume control, need to look that one up!
@@SkunkieDesignsElectronics Yeah, I’d think that’d be right up your alley. 🎶 🔊 ✨
With a 6N2P the preamp sounds really amazing. I was using the excellent Gold Lion ECC83, but the 6N2P is in a different league.
Can this be used as a preamp for a turntable?
No, this doesn't have RIAA equalization.
@@SkunkieDesignsElectronics ah yes that's what I thought. Could it be modified for phono input?

@@SkunkieDesignsElectronics Very interesting - thank you.
You didn't employ the ground lift switch, it's very useful I found. It will be interesting to see if you needed it or not 😊🤗 nice build btw!
Sweet
Isnt riaa needed for phono? If yes, what is your source with this?
Yes. However this is just a line preamp with flat (relatively) frequency response.
Not a phono stage :)

I'm just using wire sourced off amazon and same with the lead sleeves. It's just PTFE tubing designed for 3D printing.
