What is an easy way to find the outer tail (end) wrap of these Mallory's. I have no osciliscope. Would like to know so I can insert them correctly for lowest noise.

Just spit on it, it will go in!!!

That was my concern, and why I thought of puting it there. On some other amp schematics I was checking for switch placement, most of them placed switch on transformer secondary leads prior to any other electronics and if there was a choke farther downstream, and i noticed on some schematics...

When in triode mode, how dark does it get? It isnt too bad, is it? Darker than amp was before tone mods? It is liveable, isn't it? Going to do Pent/Tri mod anyway. When you come up with a fix, let me know. Have to dig thru parts box for cap for Plate/Grid. Will try it if I can find one...

Just got off of phone with Loud Tech (Crate) Pots are $1.50 (Volume--- Part designator CW-1) Knobs are $1.50 Surprisingly they had them in stock! Ordered 2 of each so will have extra incase I want to mod other V5 I have.

Great suggstion on pot and light locations. Wasn't thinking about chassis in cabinet. See there is no room for pot with chassis bolted into cab. Glad you caught me on this. Would of drilled holes and then knob would of interfered with cab.--------Thnx Will call Loud Tech today and see...

Jim, I'm going to set up the volume pot just like you have shown it on the schematic. Will mount pot on other side of power switch towards edge of panel. Am going to use shielded wire since it's a long run. O.K., understand about the op-amp now. (Just learned something-Thnx) Will place a 10k...

Thnx, Thats just what I was wondering. So, if I just leave the existing pot in place, leave C27 in place, And not put the 10k in series with the pot, I can get max gain with good breakup because I'm not limiting gain on second stage of op amp. Without the 10k in series would probably be too...

Jim, please excuse all of my questions, I'm quite new at this. Want to do the mods, but I want to understand everything that is being done so I will learn something, instead of just replacing things like a robot. Thnx again,-----Dave

So no resistor in place of C27. Do I remove C27 or leave it in place? Also in step 5 you change R17 to 270ohm 5W, but in tung's post next looks like it was changed to 180ohm 5W. Which one is correct? Thnx----Dave

Can you post schematic changes and step by step for these mods? Question on previous mods. In step 2 of board mods where you remove C26 C24 and C27, C24 and C27 are replaced with other components but C26 is not. Is this left open or is it jumpered? If not jumpered then I assume it is O.K...

3.2ohm DC resistance is average for a 4ohm speaker. 6.3ohm DC resistance is average for an 8ohm speaker. Notice the word "resistance" which has a different meaning than "Impedance". Not trying to sound too technical, but: Impedance describes a measure of opposition to an alternating current...

Resonant cavity??? isn't that like a black hole??? Yea, just trying to eliminate reasons for hum. Thnx for come-back.
