Vacuum Tube prototype / project board for 9 pin tubes

Description

We developed this board for ourselves. We do a lot of prototyping of our tube designs and we wanted to have a high quality non-dedicated prototype board we could re-use. We have now made these boards available to you.
Please see our complete project kits for 8 pin and 9 pin tubes as well as our 8 pin prototyping board.
Here is what some of customers are saying about our boards……
“Super nice boards, even better up close, many thanks for a fine product”
“Excellent product and service. Will buy again.”
"5 star product and service, GREAT value for your money!"
"Better than expected. Excellent. Thick PC boards. THANKS!"
Designed and custom made for Vacuum Tube Supplies, Llc. Our boards are made of high quality FR4 epoxy glass double sided. These boards are nearly 1/10 inch thick (0.093) using heavy clad 2oz copper. The boards have an easy to solder tin/lead coating and have solder masks top and bottom to minimize solder splashes.

Features:
Designed for three 9 pin Belton pcb (printed circuit board) tube sockets with non dedicated pin-outs
The board can accommodate any 9 pin tube
EL84/6BQ5, 12AU7,12AX7's/ECC83’s etc
Can be used for preamplifiers – guitar and HIFI
Can be used for a full mono block
OR any project needing up to three 9 pin tubes
Boards can be used for 'hybrid' designs (semiconductor/ tube)
The boards are 7.75 inch by 4.75 inch - that's over 36 square inches of prototyping space!
Tubes are spaced 2.3 inches centers to accommodate larger power tubes
Tubes sockets can be mounted on either side
6 holes (0.150) for rigid board mounting
Includes nylon board mounting hardware nuts, bolts, washers and spacers
Two bus tracks 0.1 inch wide for heaters/filaments
All other tracks are either 0.01 or 0.02 inch wide most with 0.03 inch minimum clearances
Sixteen non dedicated buss lines for power B+ etc which can be interconnected
Top ground plane for low noise connected to bottom peripheral ground plane
Ground planes joined top and bottom with 0.030 spacing to tracks and pads
Minimum pad to pad spacing of 0.15 to allow for larger components used in tube circuits
The larger pad holes 0.059 allow for large component lead diameters
Includes 0.1 inch pitch pads and interconnects for semiconductor IC's All holes are plated through
Can support 8 (eight) 8 pin DIP (Dual in-line Package) devices
80+ power buss solder pad connections
350+ small component mounting pad connections
300+ large component mounting pad connections
80+ tube pin out pad connections
70 ground pad connections
10 heater pad connections
Nearly 1000 component mounting holes
Tracks join connection pads on both sides of the board for improved connection integrity
Solder masks on both sides to minimize solder splashes
Components can be mounted on either side of the board
Can be used for point-to-point wiring instead of solder tag strips
Easy to de-solder
See our 8 pin octal prototyping/project boards. They can easily be used in combination to build a complete amplifier for mono blocks, stereo or guitar amp.
IMPORTANT - BE SAFE!
By their very nature, vacuum tubes, vacuum tube equipment and associated components operate at inherently high voltages, currents and can be very hot!
