The first step is done, the blog is online. Now it's time to fill it with content. I already have some projects in mind which I would like to show here. Most of them have been published on various forums. I'd like to put them all up on my blog so everything is documented in one place.
Some of the projects are:
A platform design for single ended power amps. This is a basic architecture which is scalable from simple RC coupled with a basic PSU to sophisitcated, transformercoupled. Employing either all indirectly heated tubes, indirectly heated driver and DHT output tube or all DHT. This concept originated around an amp which originally used a 6CB5A, triode connected but was adapted for various other tubes from 45, 2A3, 300B to 801A.
Next is a full function preamp which I call the Octal preamplifier due to it's use of all Octal tubes. This is a well proven design which has been built a few times and now goes for it's MK2 revision.
Some of you might also have read about my spud amps based on the 6HS5 and 6HV5A beam triodes.
On the preamp front there are also linestage designs using 801A or other DHTs and of course my family of transformer coupled LCR RIAA phonostages using rare tubes like EC8020, WE437A, but also more commonly available types like 6AM4, E810F, D3A. I also have some ideas about different ways to doe the RIAA equalisations. So far only on paper and simulated. But yet to be built. So many projects but so little time.
Expect some of these designs to show up here during the next months. Also in the pipe line is a more long time project. A humongues 160W SE power amp based on 851 transmitting triodes. This project has been dormant for a while but is due to be contnue this year.
But I'd also be interested in what you would like to see. Therefore I added a small poll to the page. Vote for projects you'd like to see. So far I only listed SE options for power amps. I'm more a SE guy. But that doesn't mean I won't do PP. I've done a few PP designs in the past. If there is interest in this topic I will take it up and see what I can do.
