Re: DIY Build of Douglas Self's Trimodal power amp

Nicely done. Thanks Nick! Actually I take it back :-). I just noticed you are using an Alps Blue. I take your point! Upgrade to far better pot imminent! (And Elna Silmics) This amp (with the Transporter) sounds so good to me it is now going to displace my previous office system. (which was never my...

Re: Owston ‘21: What Are You Bringing?

I will bring along my heavily modded Transporter and my CDpro2 Transport (easier than trying to bring all the gear necessary for streaming). Plus it means I can play other peoples music on it. I'll also bring along the "Douglas Self" Trimodal amplifier. (As detailed in Wireless World June ...

Re: DIY Build of Douglas Self's Trimodal power amp

Right, fully working now! Tomorrow I will move it to a place where I can listen properly on both the Class A and Class B modes. OK, now here's the question: What do people use for speaker cable these days? I am currently running it on some weedy bellwire stuff. My office system uses some NVA, I can'...

Re: DIY Build of Douglas Self's Trimodal power amp

To be fair, I think the counterfeit thing is widespread with this obsolete audio stuff. I can't fault the place I bought them from, they have been totally fair and transparent.I feel sorry for _them_ more than I feel wronged myself. I only bought 4, they probably have a load. The transistors I'm usi...

Re: DIY Build of Douglas Self's Trimodal power amp

Thanks Dave! :D Well, an update. Plus a word of caution. Everything was going well until I attempted to try the Class A mode. Then it all went pearshaped. :cry: To cut a long story short, my so called "Sanken" output transistors were in fact fakes. I started to get the idea something was w...

Re: Owston 21 ???

Count me in Steve!

Either date.

I have some stuff to present (finally!) Although my amp is currently a bit broken. (I hate it when the smoke gets out) :oops:

Re: DIY Build of Douglas Self's Trimodal power amp

Nice build Tony, very tidy. How does it sound? Ray At the moment I still have some work to do on it to complete the mode selection and power LED so it is not in a position to really set up properly but from what I've heard so far the sound is very detailed, plenty of bass and imaging is good. Compl...

Nice heatsinks Tony! :) Do you have a link to the case? https://www.ebay.co.uk/itm/273637251490 I've bought from this seller previously, very fast shipping although it does cost quite a bit for shipping. The packaging was fabulous though, no damage at all and the hardware was all there and screws f...

Re: DIY Build of Douglas Self's Trimodal power amp

Well, since there have not been any replies I'm just going to keep on talking and hope someone is watching! :D So, the pcbs arrived, along with a nice detailed instruction manual on the design and a list of parts, most of which including part numbers for Farnell, RS or Rapid. Quite a few of the comp...
