For a long time now i've been hankering after a Champ or similar, and being as i like to get stuck in and build stuff i thought i would buy a kit and put one together myself. At the same time i've got a Blackstar HT5 combo (with the 12" speaker) that has been a pain in the arse repeatedly and i never really like the sound of it anyway. Ive had to replace 3 pots on it, something else that i cant remember and last time i used it wasn't working again...
So my cunning plan is to put together a 5f1 circuit and transplant it into the Blackstar.
How does the 5F1 circuit sound with a 12" speaker? I'm thinking maybe use a Greenback.
As far as the build goes, i can solder and i've spent a fair bit of time lately reading how amps work, and i've got a good basic understanding now of what the various components do in that circuit. For a chassis i think i'm going to have make one up as copy of the Blackstar one, cant really think of a way to repurpose it, unless anyone knows different?
So yeah, thats it really. Thought i would make a thread just sounding out my idea, and if it gets that far, (and people are interested) i'll do a build log - God knows i'll need all the advice i can get! lol

It may not be quite as straightforward as you think if you were planning to re-use the transformers though - the HT5 is actually a push-pull, whereas the 5F1 is single-ended - so you'll need a new output transformer.

That's what i was hoping to hear
No plans to use the HT5 transformers, or any other electrical components - Current thinking is get a kit from somewhere like Modulus, that way i'll have everything i need in one fell swoop.

take care and good luck with it.

I recently put my silverface champ into a 12" and ended up with a decent old 4 ohm Fane "blue". But If I had to do over from scratch I'd get the biggest classictone OT to be able to use a wider range of speakers.
You can repurpose the current chassis with some work. Add a new alu sheet across the old faceplate to cover the holes etc.
Are Classictone transformers available in the UK or are you paying shipping and import tax from the US?

Next step is get in touch with Modulus and get some parts ordered!
