Hi!

Part 8 - Medium and High Frequency Signal Generators

Chapter 73:- Introduction to Pulse Generators
Chapter 74:- The Lyons Pulse Generator Analysed
Chapter 75:- Fault-Finding a Pulse Generator
Chapter 76:- Introduction to RF Signal Generators
Chapter 77:- The AVO HF135 Signal Generator Analysed
Chapter 78:- Fault Finding a Signal Generator
Chapter 79:- Valve and Transistorised Dip Oscillators
Chapter 80:- Introduction to Synthesized RF Signal Generators
Chapter 81:- The Marconi 2018 and Marconi 2019 Analysed
Chapter 82:- Repairing a Synthesized Signal Generator
Chapter 83:- Build a Good Quality RF Signal Generator for Broadcast Receiver Use

Chapter 82 will include the "OM335" hybrid amplifier module, by the way.

I am not going to deal with u.h.f. signal generators above 1 GHz at this stage as long experience reading this Forum suggests there's no immediate need to cover this field, but I may add this as a supplement if it proves necessary.

Hi!

Just a thought - you may be planning to include in another chapter, but maybe a chapter on protection circuits - protection of both PS itself and of connected DUTs. There have been quite a lot of queries and comments on this area over the years on the Forum, and it might merit its own chapter, since there's a fair bit to say.

Mike
Chapters 51 and 55 will cover these points!

Hi Chris,
Will you be including Nixie type display tubes in your publication? Also did you receive the emailed pics of the Blackstar Meteor?

Afternoon Dave!

Meteor Pics received with my grateful thanks!

I would like to feature the AVO DA112 Nixie DMM but "Nixiephoolery" prices are well to the fore – last one I saw on sale was four figures and that was a dead one, and I've not come across the circuit yet!

However, there's no reason why I can't use a diode–matrix operating high–voltage switching transistors on a DVM chip or something like the Siliconix LD120/LD130 and feature it as a "retro" DMM project!

I mentioned the nixie tube as I remember seeing a frequency counter in my dim and distant past, possibly made by Solartron or Racal.
Also do you require a circuit and photos for the Antex TCSU1 temperature controlled soldering station? Am currently repairing mine and have taken some pics of the inside etc.
Another item, that I have is a Kikusui 100Mhz oscilloscope, which uses a dual tracking power supply chip and I do have a service manual for it.

Hi!

Part 9:– Oscilloscopes, Spectrum Analysers and Logic Analysers

Chapter 84:– Introduction to Oscilloscopes
Chapter 85:– Oscilloscope Input Circuits
Chapter 86:– Valved Oscilloscope Amplifiers
Chapter 87:– Transistor Oscilloscope Amplifiers
Chapter 88:– Valve and Solid State Oscilloscope Trigger Circuits
Chapter 90:– Principles of Timebases
Chapter 91:– Valve Timebase Circuits
Chapter 92:– Transistor Timebase Circuits
Chapter 93:– Horizontal Deflection Amplifier Circuits
Chapter 94:– CRT and E.H.T. Supply Circuits
Chapter 95:– Valved Oscilloscope Power Supplies
Chapter 96:– Solid–State Oscilloscope Power Supplies
Chapter 97:– Switch–Mode and Two–Stage Regulated Power Supplies
Chapter 98:– A Special Case – Servicing the Gould 4072 and 4074
Chapter 99:– Battery Operated Oscilloscopes
Chapter 100:– The Direct View Storage CRT
Chapter 101:– Servicing the DVST – The Telequipment DM63/DM64 & HP DSVT Oscilloscope
Chapter 102:– Introduction to Digital Storage
Chapter 103:– Two Commercial Examples Analysed – the Gould OS4000 and Tek TDS 520/720 Ssries
Chapter 104:– Cursor and Readout Oscilloscopes
Chapter 105:– Fault–Finding Digital Storage Systems
Chapter 106:– Fault–Finding Cursor and Readout Systems
Chapter 107:– Component–Tester Add–Ons

Chapter 109:– D.M.M. Oscilloscopes – The Tektronix DM44 and the Soviet C1–112
Chapter 110:– Fault–Finding Oscilloscope D.M.M. Circuits

Yes, I do realize I will have to renumber the chapters I'd originally listed as Chapters 111 to 130 – I'm still formulating the contents of the S.A. and L.A. chapters, nos. 111 and up!

I think, on what I envisage at the moment, the work will be completed by Chapter 160 – (originally planned chapter 130) Building A Good Quality T12 Soldering Iron Controller.

Appendices will deal with Circuit Symbols and Units, Screw and Fastener Sizes, Decibel Tables, etc.

I'm not going to write reams of appendices as there are innumerable standard public–domain reference works dealing with these!

Hi!

One point I have been considering, is the style of circuit drawings to use, so I have decided to use the "zigzag", the "loop" and the "blob" (male connector pins) for the theory aspects and equipment built roughly before July 1975, and circuits for equipment released generally July 1975 and afterwards, will use the "box" and the "half–moon", and the "cricket bat" male connector pins!

I have decided on doing it this way as this is what most Members are most familiar with, and the appendix chapter on circuit symbols will include an explanatory note to this effect.

All other circuit symbols will be to a standardized format, as will be all the diagram lettering.

Section Headings are planned in Grotesque and Italic Grotesque for figure captions, as this style was very popular for 1960s and 1970s British T & M Manuals.

Text Typeface will be Baskerville as I find this is clearer to read with large lengths of continuous text than Times New Roman and that horrible old fashioned style "Latex".

I am in the throws of doing the promised equipment listing for your perusal. Please allow a little time for any required scans and photos, as all my manuals are paper based and for example the Kikusui COS6100A has over 120 pages to it. I will send the list to your inbox as a .doc but if you want a different format please let me know. Btw when doing doing my committee stuff, I use 'Verdana' as my font, as the number one, capitol I and small l (ell) are all shown differently, unlike some font styles.

Thanks for that Verdana tip, Dave. I do proofreading, and distinguishing between those different vertical characters is a frequent problem!

Hi!

The fonts I have chosen distinguish between Capital "I" and one, altho' there is a slight risk of confusion between Capital "I" and lower–case "L" normally the context will make clear which is intended – most "sans–serif" display fonts tend to use a lower–case "L" that is a straight single stroke.

High!

Small Review of Part Nos:–

Part 9:– Oscilloscopes
Part 10:– Spectrum Analysers
Part 11:– Logic Analysers
Part 12:– Single–Purpose Items of Test Equipment and Electronically–Operated Tools in Common Use

Parts 9, 10 and 11 are big enough to warrant revision to write each as a self–contained part or volume, and I think the revised Title for Part 12 nicely covers what's left!

Review of Appendices:–

App. 5:– Specifications, Circuit and Connection Diagrams of Ready–Designed Circuit and Module Blocks used in the Construction Projects

Hi!

For anyone interested in the AVO Nixie DVM DA112 I have won a manual for this, so the circuit diagram and theory of the a/d conversion will be covered in Part 3 Chapter 21!

Hi Chris, look for the Kerry ones, 3 sizes of bench top unit and made in 10 of 1000's in 60's to 80's. It used a proper transducer bonded to the s/s tank, not a radial mode type with poor reliability and low output.

Chris, I have a (valved) Mullard ultrasonic cleaner. I have posted its circuit here previously. I have two spare (non-working) tanks, and a full complement to components but not including the transformer. (It has been suggested a microwave trannie would work)
Cheers, Les.
