Very nice! How do you like the sound?

Wow, that looks really professional! I just finished my VSPS with 100 VA transformer in PSU and it sounds gorgeous - looks, not so much, especially compared to the above, but sounds gorgeous :P There is no hum or noise in silence, it is awesome.

now just to get the phonoclone and sapphire together.
Does anyone know what Bibio has used to connect the transformer winding wires to the pins of the rectifiers? Are they some sort of crimp join?

Thanks in advance I'm trying to make my PSU neater - tried soldering wires directly to pins and did a terrible job, then I tried varoboard as an interface, the holes in the varoboard were too small and when I tried to drill them out ever so slightly to make them bigger, the copper strip started coming off :/

Looks to me like he just soldered them on, then made it neat with some heat-shrink tube.

As wirehead.be said, looks like a direct solder + heatshrink.

Neatness for neatness sake is not worth pursuing. It doesn't have to be done pretty, as long as it is done well. Sometimes the best method is actually the ugliest.

In this case, the most reliable connection for the bridge rectifiers is a wire soldered directly to the leads. Some of the heavier bridges have 5 mm tabbed leads, and obviously a commercial build would have a dedicated circuit board, but screwing the recitifers legs-up into the case, and soldering the wired to the leads biblio did is perfectly acceptable, indeed recommended.

The heavier leads of the rectifier means you need a more powerful iron (or higher temp setting) to do this without making a mess.

still not finished my amp/clone as i run into problems :-(

anyway, i used terminals part # 3-8070 from here for connecting the transformers to the bridge rectifiers.

in hindsight though i should have just used some screwdown blocks.

if i could make pcb's then i would have done it that way using screwdowns.

i'm hoping to get back on track soon :-)

the phonoclone is working but the headphone amp is not and i have decided that i'm going to do things a little different as regards to power supply or i might just plug the phonoclone into an integrated amp and use the headphone amp in that.

What headphone amp is it that's not working?

hi Richard, its the sapphire. i've more than likely burgerd it up somewhere along the line.

i haven't a clue what i'm doing.. lol

i'm going to be getting back into putting this thing together very very soon and i'm going to have a go making some PCB's for myself to make things easier to hook up. had a look on the tube and it looks fairly simple.

the PCB i'll be trying to make is for connecting the transformers/rectifiers/output. this is what i have come up with so far.

Feel free to run it past me in detail, on the Sapphire thread or by email.

The PCB traces above look basically right, but I don't follow what you are doing with the output V++ COM V--, there are pads which don't seem to be connected to anything. The attached revision would seem to be sufficient...
