Re: What Are You Listening To Right This Minute?

Great album that one Mark.
"The Sun in September" and "Mary Emma Louise" are a couple of my faves from it.

The "Into Forever" Album with Halsall and the Gondwana Orchestra, from 2015 is also very good.

Re: Remember These?

Now I've made a firm decision about which way to go with the OTL and all the components are here, I can start the thing. The box is the first thing on the agenda and is of the 'wood surround' type, with aluminium top plate. Apertures will be cut in the front and back faces of the box to house stainl...

Re: Remember These?

My LM317HVs have shipped, so I should have them tomorrow, The Texas Instruments LM317-HV, has on-board, safe area, current limit, thermal overload protection, that "makes the device blowout proof" and the protection functions operate even if the adjust terminal becomes disconnected, so says the data...

Re: Remember These?

I'm starting to feel that this bloody thing is taking on a life of its own and soon there are going to have to be some choices made pretty sharpish and stuck to, or it'll never get boxed. :lol: So, a choice has had to be made, and I've decided to use the LM317HVT/NOPB, 1.5A, 60V regulator IC in the...

Re: Remember These?

That's a beast :shock: At least the 783 does in theory work as a starting point for further experiment. Ray and me have been toying with the idea of a mosfet CCS kit from the USA once we've got the amps going in our respective proper boxes, but that IXYS thing looks just the job for future improveme...

Re: Remember These?

Cheers Nick.
I have a few DN2540, Paul gave me years ago, but these will only stand 500mA constant draw, so they'd be right on the edge like most things where OTLs are concerned.

Re: Remember These?

All the parts have now arrived from RS. I've decided that this is going to be an integrated amp with five inputs rather than just a power amp, which would require a passive pre to do all the signal routing. There may be a fly in the ointment at the 'mo though. I had a conversation with Nick yesterda...

No prob. I can send you a drawing for use as a drilling template if it helps?
Hi Ray, I'll probably manage thanks :)

Breadboard is now bereft of bits and in the outside loo.
I'm now poring over the layout. Can't afford to mess that one up.

Re: Remember These?

Thanks Ray. That'll save a lot of messing about.
I offered the sockets up to the boards yesterday and as luck would have it, the socket tags fit in the holes fine. Nevertheless, thanks for the heads up on that possible issue.

Re: Remember These?

The "Not OTL" breadboard has been removed finally from the room, in preparation for being plundered for transformers, chokes, bridge rectifiers and caps. I'm back to the solid state situation for now but as they say, "No pain, no gain" :lol: I'll populate the driver boards tomorrow, and start making...

Re: Remember These?

Two input/driver PCBs arrived today, courtesy of Ray.

No excuse for not starting now. :D

Thanks for those.
