Ever wanted your own Valve Amplifier?

Why not build your own?

This listing is for a kit form Single Ended Class A Stereo Amplifier based on ECC83/12AX7 preamp and Shuguang EL34-B output valves (which are included), but may easily be adapted to use output valves such as 6V6 or 6L6.

The kit includes the electronic components, PCB, sockets, 1 x ECC83/12AX7 and 2 x EL34 output valves, but does not include power or output transformers. The assembled amplifier PCB is pictured here for illustrative purposes only as the kit will require assembly.

This amplifier will drive 4 Ohm or 8 Ohm speakers with a suitable pair of output transformers (not included, contact us if you wish us to order in suitable transformers for you) and requires a 1V audio input signal for full output power. It may be connected in Ultra Linear mode using a transformer with a suitable tap.

Basic assembly instructions included but this kit does require extensive soldering and some high voltage testing and is only suitable for the experienced constructor.

This kit board is also available ready built and tested, ready to wire into your own chassis. If you require the board assembled, see our other listing for details.

As a kit, the build quality is very much under your control and due care should be taken to ensure safe solid mains supply and HT wiring and suitable fuses should always be incorporated in the live mains and HT+ supply lines. This amplifier must also be earthed for safety.

This amplifier will when completed require a power supply with an HT output of between around 200V and 320V DC at 100mA and a heater supply of 6.3V AC @ 3A. No further power supply details or schematics are given as this is a module designed to be used by an experienced constructor who can make such a supply or retro fit it to an existing radiogram etc.

Other Valve Amplifier Turret Boards built and fitted with components, including your own custom designs, are also available - contact us for details and a quotation.

This is NOT possible if you have already paid for any of the items you are ordering.

If this option is not offered in the listing, please use the following listing to pay the extra cost of this.

Tracked & Signed supplemental charge to Italy

Also note that orders sent to Italy may take MUCH longer than eBays estimate to be delivered and, whilst some orders do arrive within a week or two, many orders sent to Italy are not delivered for three or perhaps even four weeks! This is entirely outside our control, as we ship within two working days and once your order is in the hands of Poste Italiane, there is nothing we can do to get it to you any faster.

Please DO NOT send messages with the title "Item not received" as these open complaint cases against us and damage our seller rating! Instead please use the general "Other" heading to ask about your delivery if several weeks have passed.

Lastly, all please note that when eBay asks you "Did the item arrive on or before" their estimated delivery date, it also damages our seller rating if you answer "No", so bear in mind that we always ship within two working days, so if you answer "No" because your local postal service (especially in Italy!) has taken weeks to deliver, you are punishing us, not them!

Thank you all for your kind consideration of the above and remember that we will always do our very best to sort out any problems or questions you may have related to your order if you contact us using the "Contact Seller" and (if the choice is given) "Other" ask a question of seller options.
