Phase splitter board noval pin9 grounded
These are very simple phase splitter boards, I imagined these used with 6N1P or 6N2P. These are roughly equivalent* to the 6SN7 and 6SL7 in 9 pin noval package*
These should be workable boards, if you need a tad bit more gain you can decouple the first tubes cathode.
Sockets are mirrored, with a 3mm hole in the centres of the sockets to mark out the holes on the chassis.
PM if you want me to make slight alterations.
*Not entirely electrical similar but made as a miniaturized replacement in new equipment.

EL84 ECC83 EF86 amplifier PCB
This board is a real treat for those who want to build a decent EL84 PP amplifier that is quite compact as well. Dimensions are 100x100 or about 4x4''
I don't know if these have issues, if anyone spots any except for some of the missing values please let me know, i'l have the mods replace the gerbers with ones that are correct.
The circuit is from a audio magazine, i cannot post the complete article due to copyright concerns.
Quite straightforward design with EF86 ECC83 and EL84.
Like always, tube sockets are mirrored and fitted with 3mm center holes.

Tektronix iron power supply board.
Tek iron from scopes, regardless of how you feel about gutting these can be used for tube amps.
This is a board for the three main HV windings. They are about 370VAC in total giving 480VDC under load at 250-300mA depending on exact transformer model.

PSU board 4x 25mm snap-in DO-201
These are really nice boards if you are sitting on a box of 25mm diameter snap-in capacitors.
I couldn't find the eagle files so i could output a plot, but these are simple boards anyway.
The suggested fuse holder is a ZHL15 from TME if i'm not mistaken. Diodes are dependant on your current and voltage requirements. I use SB540-560 here for low voltage work.

UniversalHV REV0.0
These boards are a treat. Dimensions are 50x150mm.
These are some of the best selling boards, i have an updated version that i will keep to myself.
The MKP10 caps will not fit on this board.
MISSING A BLEEDER RESISTOR, BE SURE TO BOTCH ONE IN BEFORE USE OR THE RESULTS MIGHT BE SHOCKING TO SAY THE LEAST.

Voltage regulator negative TEK 567 based ideal for high power SE
This is quite unique, and very useful if you are building tube amps that need a stiff negative supply. For example GM70 amplifiers in fixed bias.
Can be made to provide from around minus -100 to minus 200V by adjusting the resistor values of the circuit. See the original circuit from tektronix, its fairly easy to make adjustments for different output voltages, this i am willing to help with.
Very smart circuit by tektronix, the high mutual conductance coupled with the transistor VAS creates ample open loop gain for this control element.
An external pass tube is connected at the Anode grid and kathode terminals, i only wanted to put the control amplifier on a PCB and have a free choice in pass tube.
I have also attached the Eagle files for those who want to panellize the boards for economy.
Sockets are on the other side compared to the components, made for under chassis mounting.
PM if you need a custom version.

Ketje's/Mona's regulator 6.3VAC to 6.25VDC
This is a prototype board for a low dropout regulator that is supposed to deliver 6.25V from a 6.3VAC transformer winding.
Credits for the circuit go to Ketje.
This board uses SMD components, MELF0207 resistors, so not fit for noobies
Designed around this heatsink: RAD-A5723/50-AL STONECOLD - Koellichaam: geextrudeerd | met ribben; natuurlijk; L: 50mm; W: 78mm | TME - Elektronische Componenten
You can substitute a BD140 for the VAS/driver transistor.

Fixture board for 4mm jacks
This is a board to make a 100x100mm fixture for tubes or anything else, you are meant to get the 4mm banana jacks with M4 thread on one side. these can be found for cheap on Aliexpress.
My idea was to mount a 2mm thick piece of FR 4 100x100mm on top if this board, drill a hole in that for a socket and use this board in 2.0mm as the foundation of the fixture.
