-------Do you use one 5965 tube and two 6v6 tubes per channel? -------

Yes. The 5965 is a dual triode, meaning it is a single tube containing two triodes.

-----The power supply looks like it one 5965 tube and one 6v6 tube, is this the case? do you just pick one of the tubes to use?---------

The power supply needs to be connected to all of the tubes. What looks like a single 5965 represents all of the 5965 tubes in the amp, meaning that pins 4, 9, and 5 of every 5965 need to be connected as shown in the schematic. Same goes for the 6V6 tubes.

-------Where exactly is the output on the schematics?-----

The output is in the audio circuit schematic, coming off of the 125D output transformer.

thanks!

Hey,

You don't necessarily need to have a wealth of experience with electronics in order to put this amp together; as long as you can follow a schematic you can build it. The reason I wouldn't recommend this project to someone inexperienced electrically is the safety issue. The amp runs at a high voltage and has a lot of current going through it, so the risk of shock is quite high in comparison to many lower power electronic projects.

I would say it took a weekend or two to assemble the amp, once all the parts had arrived.

There are a lot of reasons for wanting to make a tube amp. First of all, they're just cool. They glow, they're glass - they have a high retro appeal. Secondly, they do sound great. Mostly though, it's a great educational experience. Modern electronics don't really use tubes like they used to (with the exception of boutique audio equipment and guitar amps) so building a tube amp is a good opportunity to learn about an old technology as well as give you some perspective on the development and history of electronics.

thanks!

Hi, I didn't keep track of the cost very well while I was building it, but I would say that it was somewhere in the area of $150-$300. thanks for your interest!
