TECHNICAL SPECIFICATIONS

TUBE COMPLEMENT: (5)

1x octal base 6SN7WGTA dual triode NOS

2x 12B4A NOS SINGLE TRIODES and adapter with teflon sockets

2 x 4 pin base 211 VT-4C large triode [ PREMIUM NPS VALVE ART ]

1ST & 2ND STAGE

The 1st stage is the voltage gain followed by the 2nd stage driver. We are now using Teflon capacitors for the signal transfer.

OUTPUT STAGE

Single ended and self-biased the 211’s drive the refined double C core Bartolucci transformers with an improved low frequency response and theoretically lower distortion. Individual selection of speaker load impedance (4 + 8 Ohm) is accomplished via dual contact high current switches. (40 ampere rating)

ALL STAGES

Operate in class "A1" single ended. Self-biased...no adjustments (tweeks can swap valves without consequence) < ZERO FEEDBACK > No LOCAL or GLOBAL FEEDBACK of any kind!

Upgraded with all Teflon signal capacitors for the ultimate in performance and reliability

MECHANICAL CONSTRUCTION

CIRCUIT BOARDS

PCB's using precision double turret terminal posts

Our fixed terminal hand crafted printed circuit boards are a new technology used in construction and is a first in the industry. Again Wyetech Labs is at the forefront and is always looking for ways to improve reliability and construction.

Some of the components are mounted on double turret terminal post, especially the power resistors, which improve the heat flow. These boards are then held elevated from the surrounding metal chassis to avoid any capacitive coupling between components.

The double turret terminal post are first swaged to the printed circuit board and soldered into place. After that the boards are then hand assembled with parts soldered to these terminal post using silver based solder. For wiring to and from the boards Weco screw down terminal connectors are used to make connections between the various components and to facilitate easier replacement of parts for future reparability and long service life. This technique will result in much faster trouble shooting and repair in the event of any failure requiring servicing.
