My new amp. SE 6N8S + 6P3S (triode mode).

Great looking amp. What output transformers are you using?

Here are some follow-up photos of my ultra rare Rodango Bass Guitar Amp. It is the only one in the world! It uses a 6SN7 preamp tube, a 6L6 for driving the splitter transformer and 4-KT88s in parallel push-pull. The power amp design was lifted from the Fender 300PS and the rest is my design and all of it is my construction. Custom made case, panel and plate.

Controls are gain and volume (front) hum and balance (rear) I have calculated its output at around 235 watts.

I just built a phonostage based on: RJM 6dj8/6922

Here are the pictures of my RJM phonostage using 6n1p instead of 6dj8/6922:

On the left is my 12au7 VA/CF preamp, on the right (black chassis) is my RJM phonostage and below is my EL84 driven EL84 parafeed amp.

I'm using transformers from old TV-set with mods. In plans change them, becuase this transformers so small to give me good sound. I hope you understand that I mean, excuse me for my english.

... Wondering if those high temp wire wound resistors cause any questions/problems? Is this usual or do many 'philes replace 'em?
