DIY Tube Amp Help

[Eafnb]

I'm looking for parts for a tube amp project I found recently, and it will be my first tube amp project to undertake (https://www.audioxpress.com/article/mighty-mouse-a-pp-25l6-amplifier). I managed to get some of the smaller parts like the switch, pilot lamp, fuses, and fuse holder. The problem I have so far when reading the article and parts list, is that I apparently need duplicates of the Triad transformer (T1) (https://www.digikey.com/product-detail/en/triad-magnetics/VPS230-190/237-1270-ND/666156) and the Radioshack 273-1512 transformer (T2). Yet when I look at the complete product that the OP made in the pictures, he used only one of each. I know that the other components like the capacitors, resistors, ICs, diodes, and toroidal transformers have to be in pairs for stereo (all of which I haven't bought yet), but do I really need pairs of the T1 and T2? I am also open to any recommended changes, modifications to the schematic/parts, and advice.

You can use a single power supply shared between the two channels, in which case you need only one set of power supply components. Alternatively, you could use a separate power supply for each channel, in which case you need to double up the power supply components.

You see this site? It may have more info on that amp. Its P Millett's site. Scroll down and you will find that amp.

I see, but based on the picture the person seemed to double up on the components and kept one power supply to achieve stereo, so is that okay?

I looked on the site, unfortunately he only worked on, "The Mighty Midget". He didn't work on "The Mighty Mouse" which is what I'm planning to work on since I already got a pair of 25l6gt tubes.

Single power supply is fine for a stereo amp, so long as it has enough current capacity to run both channels. Most stereo amps are built that way.

You'd need 4 25L6 tubes to get a stereo amp.

Gotcha, I'm in the process of getting another pair at the moment.
