Side A

Recording & transfer

Getting music off reel-to-reel, cassette, DAT and MiniDisc, keeping the files safe, and making simple stereo recordings of your own.

Reel-to-reel and cassette to digital, without hurting the tape

Read the box, look at the pack, spot sticky shed before it gums the heads, match track format and speed, set azimuth by ear, decode Dolby only when it was used, and capture once at 24 bits.

MiniDisc to digital

SP or MDLP, NetMD or Hi-MD, USB upload or real-time optical capture: which route fits your discs.

Point-source stereo recording

Two microphones, one position: XY, ORTF, AB and Blumlein compared, with the standard angles.

A capacitor does not know the plug is out. Discharge it, measure it, then touch it.

The first rule of every bench job, from What fails in vintage hi-fi and Vacuum tubes in hi-fi.

Side B

On the bench

What wears out in vintage amplifiers, receivers and decks, how vacuum tubes work in hi-fi, and the service documents that explain it all.

What fails in vintage hi-fi

Capacitors, pots, relays, belts and bias, and why safety comes before any of them.

Vacuum tubes in hi-fi

Preamp, power and rectifier tubes, matched pairs, testers, bias, and lethal voltages.

Service manuals and schematics

Where legitimate copies live, what a service manual contains, and how to read a schematic.

Side C

Buying & collecting

Buying used gear with open eyes, tracking down rare components, building a good system for very little, and the makers behind the classics.

Liner notes

Quick answers

All questions and answers

My reel squeals and leaves brown gunk.

Stop: that is sticky shed. Clean the heads and read the tape guide before playing it again.

Does every old amp need recapping?

Not automatically. Measure, work one area at a time, and follow the service manual.

Why won't my MiniDiscs upload?

NetMD uploads were restricted. Capture from the optical output, or see the MiniDisc guide.
