6T9 Valve Audio Amplifier.

The inspiration for this project was given by Mark Houston who wrote up his experiences of making and modifying the Spare Time Gizmo amplifier described in Nuts and Volts magazine. Marks experience was that with a few mods the quality of this cheap valve audio amplifier could be able to out perform many of the expensive Solid State counterparts.

The Printed Circuit Board arrives.

The components arrive and now the assembly can begin.



 
Continuing the assembly.

The Iron arrives, now for phase two of the assembly.

 This is probably the most tricky part, cutting and drilling the baking tray for the top cover.

Assembling the 6T9 Tube amp ready for wiring.

Putting the pcb into the tray and aligning and securing it into the created holes was a slow process.
Now it all has to be wired up.

                                                                                                                                                                 



With all the wiring done it's onto the testing stage.

My next step is to clean all the wiring up and mount it all into a more respectable case and dispense with the Oven Dish. Something like this from Hammond Manufacturing. 

So now the 6T9 Tube Amplifier can be nicely boxed into this lovely base that was made by Martin, my friend, out of cherry wood.

The hardest part was drilling the 3mm copper sheet for the top cover.

That's the end of the Oven Tray. 

Here is what the finished amp looks like

And with the Fostex206 high sensitivity speakers there is much more volume and clarity.
