Made for the job

What's built in for hi-fi & amplifiers.

Amplifier checklists

Left and right output, DC offset in mV, bias in mA, hum and noise, pots, inputs, phono stage and speaker switching.

Board viewer and readings

Open .brd, .bdv, .bvr and .cad board files, tap a net and save diode, voltage or resistance readings on the job.

The right service manual

One tap searches for the model's service manual; save the PDF once and it shows on every unit of that model.

Checklist and templates

Every hi-fi & amplifier job starts with the same checks.

This is the checklist the app adds to a new amplifier and hi-fi job, word for word. Each item is pass, attention or fail, adds up to a health score from 0 to 100, and can carry a note or a measured value. Critical items cap the score when they fail.

FAQ

Hi-Fi & amplifiers: good to know

Does it handle vintage amplifiers?
Yes. Devices don't need a catalogue entry: type brand and model, add serial and notes, and use the amplifier checklist and templates.
Can I record measurements?
Yes. Checklist items take a note for values such as DC offset or bias, and the board viewer saves readings next to what a good board reads.
Is a schematic library included?
No. The app links you to a search for the service manual and keeps the PDFs and board files you add, included in your backups.
What does it cost?
599 kr. a month or 5.990 kr. a year, excluding VAT, for the whole shop: every device and every user. Try everything free for 14 days first. See pricing.
Do my devices sync?
No. Each installation keeps its own records and there is no automatic sync between devices. Move data with a backup. How data is stored.
