That's a good argument for using the Tubelab SSE board, and making a 'plain' version of the amp with basic budget components... IMO.
The Tubelab SSE won't need any tweaking to work properly.
The only 'difficulty' with using a PCB that has the tube sockets mounted on the board is that you need to be fairly accurate in drilling your chassis/case. But there are drilling templates for the SSE chassis, IIRC, and you can use the board itself (before you fill it with components) as a template for marking out the chassis. Using a large chassis helps to ease the layout of the 'off board' components.

I forget if you mentioned whether you were planning to build your case/chassis, or buy something, or a combination (Hammond chassis and wood endplates, for example). What sort of shop equipment do you have?

Again I would suggest a tubelab project. I hadn't touched a soldering iron in years and was very pleased with the result. I would describe the tubelab approach as a recipe. There are lots of ways to modify and lots of suggested ways of doing so on the DIY site, but you can also follow George's instructions and get a great amp. I don't believe I spent much more than $300 on the project. Most of the money went toward the transformers. The Edcors are a great value if you have the patience to wait for them.

good luck

Well if you build a tubelab amp with your own layout etc.... then you may or may not need tweaking. Most of these circuits are so simple that anyone can help you with them and the only variable is how you implement it. For example you could build a well known circuit and still have hum or ground loops which happens all the time, the troubleshooting would be the same regardless. Really, in my opinion as long as you aren't using any global feedback around the transformer you shouldn't need to tweak anything.


The tubelab SSE is a good choice btw.

Ok so I have taken this over to the Tubelab vendor forum here, I am going to blow my budget wide open and go for a Tubelab SSE In Triode Mode using some 6C45's hope to be pushing 8-10 watts. Just have to get a couple of more questions answered from George and I'm gonna pull the trigger on the parts order. :eguitar:Be sure to check it out and I will keep you updated.

Cheers :cheers: :eguitar:
