5F6 with reverb (Tubenit schem) someone developed a layout ?
« on: August 27, 2018, 10:23:03 am »
Hi guys

a member of DIYItalia want to convert a Carvin Valve Master into a 5F6 with reverb

at music-electronics-forum.com I've find a schematic that is attribuited to our friend Tubenit

(this is the thread http://music-electronics-forum.com/showthread.php?t=23241 - post #17)

and would like to know if someone developed a layout

Many Thanks

Franco

Hey Franco,

Always good to see you on the forum!   :thumbsup:

There is BOTH an editable SCH schematic and matching layout here  (see Reply #1) :

https://el34world.com/Forum/index.php?topic=571.0

CHECK it for errors as this is one I drew up quite a few years ago.

With respect, Tubenit

Looking at the schematic idea of the Bass 5F6-A with reverb,  ……….. you could use a mosfet CF and free up one 12AX7 triode for a stronger reverb driver using a 12AT7?

PLEASE check carefully the layout to see if it matches the schematic correctly.  IF there is a discrepancy, go with the schematic.

Also …………….

Here is the editable layout for the 5F6-A . 

With respect, Tubenit

Franco,  do you have ExpressSCH or j-schem where you can edit the editable schematic and layout?

I got to thinking some more about the Bassman 5F6-A idea using a mosfet CF and having reverb added.  So I redrew the schematic and tried to draw a layout to match it.  CHECK for ERRORS!   IF there is a discrepancy, go with the schematic information.

Things to note:

2 inputs instead of 4,  split cathodes on V1,  mosfet CF,  & an additional stage of filtering.

Just an idea to consider.

With respect, Tubenit

You are quite welcome!   Just thoughts to consider for you.  They may or may not be useful.   :icon_biggrin:
