I cleaned my papers and found the following building instruction for an OP-amp based treble booster from 1983.

Hey everyone.

I'm trying to source out Brian Wamplers beginners guide to effects. I am willing to pay for it but can't find it anywhere...
Anyone know where i could acquire it?

Thanks

so i been messing with russian analogs of more common tubes, and my new fav is the 6n2p. they're cheap, robust, plentiful, and have a really great presence in the midrange going on.

they're only for fender style 6.3volt heaters.... some 12ax7's sockets are wired up for 12 volts, the 12ax can do 6 or 12, but the 6n2p can only do 6. but 6.3 is fine.

to start, go to tubedepot or whatever and get some socket savers, the kind that have a screw running thru them. check the pics.

unscrew...

Next year I'm planning on building a marshall 18w-like tube amp. I got everything but the chassis and transformers. Since I have plenty of time before I'll start to build the amp, I've thought about winding the transformers myself. Any good books or guides on power and output transformer designing and winding?

I remembered I had this on an old HDD from when I had one in to repair.

From an article:

Back in the late 1950’s, it was
conclusively seen that potting your
circuits in epoxy in no manner offers
any design secrecy whatsoever. In
fact, epoxy potting will always have
the exact opposite effect.
First, any reasonably good design
engineer could select a black box
approach and carefully look at the
inputs and the outputs of the circuit.
From the circuit’s size, cost,...

I have been using this site for a long time... never thought to post a link here, until now. I kinda like it although I am not sure how useful it is but, what the hell.. They have damn near everything from full on tube amps, preamps, solid state, pedals, VST's you name it.

Another good one!

Unlike most books on filters, Analog and Digital Filter Design does not start from a position of mathematical complexity. It is written to show readers how to design effective and working electronic filters. The background information and equations from the first edition have been moved into an appendix to allow easier flow of the text while still providing the information for those who are interested.

The addition of questions at the end of each chapter as well as...

I found this site a while ago and forgot about it until I was searching for something else today. Most of my test gear is old as it is stuff I saved from the trash when I was at work.

And select option 1.

Here's a PDF I just created of some articles on how to use an Oscilloscope which I found in my set of 6 Talking Electronics notebooks, thought the info could be of use to members who have just recently bought themselves an oscilloscope of some kind, the PDF is about 6Mb in size, enjoy!!.... :thumbsup

Oops, seems the file is too big to post here so I'm going to have to sort out putting a Dropbox link here, just bear with me..... :thumbsup

Okay, here's the link:

I have just seen this linked on another forum (

Hi FSB fellows, another good book!
The audio amplifier is at the heart of audio design. Its performance determines largely the performance of any audio system. John Linsley Hood is widely regarded as the finest audio designer around, and pioneered design in the post-valve era. His mastery of audio technology extends from valves to the latest techniques. This is John Linsley Hood's greatest work yet, describing the milestones that have marked the development of audio amplifiers since the...

Hi, to all interested!

Providing examples of applications, this handbook examines the underlying technology of each type of power vacuum tube device in common use today. The author reports on new development efforts and explains the benefits of specific work. Basic principles are discussed, and supporting mathematics are included to clarify the material presented. Extensive technical illustrations and schematic diagrams aid the reader in understanding the maxims of the subject.What's New in...

To whom it may concern!

Product Description: When intending to build electronic filters, young engineers should be aware of the fundamental principles while not getting bogged down in intricate and elaborate mathematical aspects. A presentation of the basic principles supplemented by numerical programs illustrating the design technique will fulfil these requirements.

There is not much by way of competition in this area. Much of the existing competition is older and does not include many of...
