How to order our PC boards: 

 

  NOTICE:

  We will be out of town starting on July 30. The anticipated return date is August 15. All PC board orders received by July 28 will be shipped in the usual 1 to 3 days. There will be no shipments while we are away. Any orders received during this time will be shipped on my return.

 

 

 

  I currently show amplifiers on this web site that are made with two different PC boards. I receive e-mail every day asking about my “SE amp board”.  There are two different PC boards available. If you are inquiring about, or ordering a PC board, please specify which board you are referring to.

 

 The Tubelab SE

The Tubelab SE board is used for a "no compromises" amplifier that uses DHT tubes like the 45, 2A3 and 300B. It is used primarily for constructing a high end DHT amplifier. It is not uncommon for a user to spend $500 to $1000 USD for a complete amplifier, although it is possible to build an amplifier for lower cost. The Tubelab SE board was never intended to be a beginner’s level project, in fact I didn't intend for it to be sold commercially at all when I designed the board. I have been using it to construct SE amplifiers for about 4 years. The output tubes operate in fixed bias, requiring measurements, and adjustments on a live board. External connections to the PC board are made by soldering wires to the board. The assembly manual, schematics, and theory of operation are all on the web site. At this time that is the only documentation available for the Tubelab SE board. More info is being added as I have time to write it.

The Simple SE

The Simple SE board is used to make a simplified SE amplifier that uses indirectly heated tubes like the 6L6GC, EL34, KT88 and 6550. This board is used to construct amplifiers from a basic low cost design to a high end triode mode amplifier. Most amplifiers are expected to cost between $250 and $700 USD, although you could spend less if you have some parts (transformers and tubes), and it is always possible to spend more in this hobby. The choice of output tubes are all pentodes, which can be operated in Triode mode, Ultralinear, and Pentode mode. This can be switch selectable from the amplifiers front panel. The output tubes operate in cathode bias mode, requiring no adjustments.  External connections to the PC board are made through the screw terminals. The parts density is about half of the Tubelab SE. The PC board was designed to be assembled by people of all skill levels. The assembly instructions are written with this in mind. There are photographs of every step from the start to final amplifier construction. More details are being added with each web site update.

If you are interested is building an amplifier using one of our boards, please read over the documentation on the web site. Decide if the Simple SE or Tubelab SE amplifier projects are within your capabilities. Understand that my support capability is somewhat limited for the immediate future. I don't mind answering a few questions, and many of these are used to improve the manual, but I can't possibly teach you basic amplifier construction via e-mail.

At this time I have only blank unpopulated PC boards available. I do not sell parts, kits, tubes, assembled PC boards, or complete amplifiers. I simply do not have the time or financial resources to stock, inventory, and kit all of the individual parts to offer amplifier kits. Parts packages, partial kits, and complete kits may be offered in the future.

The boards that I currently stock are available for $35 USD each. I can ship 1 to 4 boards to locations in the USA for $8 in a Priority Mail envelope (the post office recently raised their rates).

The US postal service recently changed their low cost international shipping service. They changed the name, eliminated the small flat rate envelope that I have been using, and raised the rates. The good news is that they have added several countries that were not previously served. I can ship 1 to 4 boards (in the large envelope) to international locations that are served by Priority Mail International for $14 USD. These locations can be found on the USPS web site.

At this time I do not have the ability to ship to other international locations. The rates that Fedex, UPS, or DHL charge do not make sense for a single PC board.

Payment can be sent via PayPal. Make sure that you specify which board you are ordering and the quantity you want in the instructions box. Include $8 for shipping and handling in the US or $14 for international delivery.  My email address is located at the bottom of this page. I can not put the email address in plain text anywhere on the web site because of spammers.  Payment must be in US dollars. If you do not want to use PayPal, you can send us a money order.  Make sure that the money order is in US dollars and can be cashed in the US. The address is:

Thanks for the interest in our PC boards:
