This blog is concerning ordering, parts, assembly and some brief sound review of the two new circuits designed by Salas.

The DCG-3 is a new preamplifier design. It offers 10-15db of gain, and can use several different types of input JFETs.
Here is the preliminary values in the schematic.

Here is the prototype board

Here is the Actual Production layout

The DCSTB is Salas first offering of a series regulated supply. It is very easy to assemble and includes two board assemblies off one power supply. This is a somewhat 'greener' approach and requires less waste current than say it's SSLV1.1 or BIB board equivelant....

Here is the F6 board rendered by CRT and some help from others.

It's convertible premise is to be able to swap out transformers using daugter cardsand be able to swap out variations on the schematics Nelson Pass presented at the 2012 Burning Amp Festival.
Additionally, places for two pairs of 2SK/2SJ are here to allow GR's to be used to allow for higher than 8ma IDSS without degeneration on the front end. If you have 8ma IDSS BL grade for use here, than your all set.
You can use standard power resistors or 5MM thin film type.

Here are some of the daughter cards that mount to the main board. They are available for Jensen, Cinemag and Onetics Quadfilar transformers.
These are mounted with 2 2x10 @ 2.54 mm pins. Note the PC PINs of...

Here are some pictures of the Power Supply that CRT and myself designed for use with the F5T and F6Convertible design. It is meant to be both compact, have adequate capacitance, and be able to use the recommended MUR3020W or similiar diodes. They are 2mm thick boards with 3OZ copper thickness.

(Updated boards take now 40mm wide caps and are larger measurements below and new pics)

Boards measure 108mm wide x 192mm long. The diode boards are 35mm x 54mm each.

This last weekend I replaced the IRFP240 in my F2 Clone with the R100 SouthSemi Power-JFET.

tubes-guy used psychic powers to control my mind and force me to do it.

The bias dropped off the bat. I re-biased and gave it an A-B listen to the standard channel. Seemed to be a bit 'cleaner' sounding the the default channel.

Nelson has recommended the following changes to the circuit, which I hope to implement soon. I will be re-wiring these on Peter Daniels boards.
The Peter Daniel boards are still available I believe.

Papa sayz...

The F2's that I have updated with the JFETs need the
following changes:

R6 = 47k (changed to 8.2K of FW Site)

C1 = 10 uF

Z1 removed

The potentiometer must be re-adjusted for minimum
distortion at 4.5 watts (symmetric clipping) and readjusted

Here I am going to post some semi-commercial information regarding the minikits.

BIB or SSLV1.1
Make sure to read the full BiB build manual before ordering parts. The link is posted below.

It is essential you understand and purchase for the correct voltage type and range you need for this kit and additional parts.

The purpose here is to report what parts are included in the minikit, and which are not.
This will assist builders in getting the correct parts that are not included in the minikits.

The minikits are made for one of the three sections of the PCB. The board itself can hold two positive and one negative rail type supply.

The kits are purely optional, and are sold to assist the buyer who may not be able to access the resources needed to gather the specific parts.

There are four kit types described below. IRF for voltage 5.5v...
