Re: closest 6L6 circuit to 5E3-like tone?
After visiting with my bro over Thanksgiving, and hearing his VHT 12/20 and what he wants, there are some changes. Current thinking (this is pretty much set in stone): Triode input with bass cut -> 12/20 fixed tone stack -> 12/20 tone and volume controls -> possible cathode follower into external lo...

Re: Tweedle Dee 10k phase inverter pot safety question
^^ thank you both. Yes, the concept is to be able to tweak it from the front panel. :) I've read that the best clean PI tone setting is different than for the best overdrive tone. If it can be done safely, of course. I was reading the schem as one side of the pot being a little less than 1/2 B+3. I ...

Tweedle Dee 10k phase inverter pot safety question
I'm in the late stages of working up a 5E3-like circuit for my brother (2x5E3 with some tweaks). I'm thinking of putting Dumble's 10k balance trimmer in the phase inverter. I do not want to add any risk of electrocuting him into the plan. ATM anyways. Would it be safe enough if I used a good quality...

Re: closest 6L6 circuit to 5E3-like tone?
Bad form to reply to myself, I know :) Just a shout-out to my friend profusiac. Pm me if you see this post (TAG's email notification system is busted, so my reply might be delayed). Back on track: Going with a quad of 6V6 for certain. I have two donor chassis lined up. My brother gets one. I'll have...

Re: closest 6L6 circuit to 5E3-like tone?
^^ Thank you.
Thanks to everyone for their info and experience. Very much appreciated!
Now I have some thinking, parts ordering and soldering to do.

Re: Trouble staying logged in
Aaannd - it's back. Oh well. Earlier, I was seemingly able to recreate it by: (close all Firefox windows) open new FF window log into TAG open a second FF tab log into TAG click on any topic <f5> on the first tab: logged off Fwiw, it looks like it might be related to switching tabs on TAG. Wish I co...

Re: Trouble staying logged in
It seems significantly better. Here's an hour of black box testing: 8:55 pm logged in 8:58 pm submitted a reply to another topic surfed TAG, then searched for 5e9a info, opening other tabs and so on 9:04 visited this page and used <f5> to perform a webpage refresh: still logged in surfed, etc 9:20 <...

Re: closest 6L6 circuit to 5E3-like tone?
Thanks very much, that's really useful. I'm trying to get my head around calculating power supply resistor values.

Re: closest 6L6 circuit to 5E3-like tone?
^^ I was also thinking that I don't know the power transformer's designed secondary voltage, nor whether it will change because of modern wall voltages. I'm going to approach it in the following manner: retain the dropping resistor network, but replace the existing electrolytic caps, check the value...

Re: closest 6L6 circuit to 5E3-like tone?
@Bear: thank you and I'll definitely look into the 5B6! @brewdude: that's pretty much exactly where I'm going. The only things I'll need are power supply caps, a VVR (or components to make it) and an output transformer with 4/8/16 secondaries. I have some decent, new coupling caps and signal & dropp...

Re: Rocket Documents
Thank you, Martin! Selected Save As, renamed it from "file.php" to "rocket.pdf" in the dialog, saved it and opened it. All set and good to go.
I was hoping it wasn't somehow related to the board logging some of us off unexpectedly.

Re: Trouble staying logged in
Same here except less frequently. I'm running Firefox 60.0b14 (64 bit), on Windows 7. If I can figure out a pattern, and ideally a way to recreate it, I'll report back. Until then, I'm doing a copy before submitting posts, just in case I need to log back in & paste it back into a fresh reply. edit: ...

Re: Rocket Documents
Hey folks! It seems like the Rocket schematic linked on the first page/post is inaccessible. When I click on the BOM and layout, they appear as expected. When I click on the schematic link, I get prompted to download a file named "file.php". Attaching a screenshot (large to capture the details). The...

Re: closest 6L6 circuit to 5E3-like tone?
Fantastic. Thank you!
The organ OTs are all purpose-built for a specific output impedance, and my brother wants at least 8 and 4 ohms outputs, so the 40w one you've posted is ideal.
I'll build it up and debug it using the old organ OT, then swap it out.
