Radio receiver repair
Radio silent, humming or not picking up stations? We repair valve and transistor radios — VEF, Grundig, Sony, Tecsun. Estimate first, 3-month warranty.
A radio that won't switch on, hums with 50 Hz mains noise, crackles when you turn the volume knob, stays silent on some bands or has a tuning knob spinning freely — each symptom points to a specific assembly: dried-out power-supply electrolytics, an oxidised band switch, a worn potentiometer, a snapped dial cord or valves that have lost emission. We repair radio receivers at component level, from pocket transistor sets to large valve radiograms.
Our particular speciality is the radio classics built here in Riga: VEF Spīdola, VEF 202 and VEF 206, the Selga and Riga-103 from the Radiotehnika plant, and Rigonda valve radiograms. Factory spares for these sets are long gone — we source compatible capacitors, transistors and valves, clean switches and restring dial cords. We also service Western classics (Grundig, Telefunken, Philips), modern world-band receivers from Tecsun, Sangean and Sony ICF, and tabletop radios by Roberts and Tivoli Audio.
An old radio is often a family keepsake, so we are upfront about what can be restored and what is not worth repairing. Diagnosis takes place at our service centre, and the estimate is agreed before any work starts — the decision is yours. All work and fitted parts carry a 3-month warranty.

Restoring the Riga-built radio classics — VEF and Radiotehnika
The VEF Spīdola, one of the first mass-produced Soviet transistor receivers, went into production in Riga in the early 1960s, and the portable VEF 202 and VEF 206 became arguably the most recognisable radios of their era. The Radiotehnika plant built the pocket-sized Selga, the portable Riga-103 and the Rigonda valve radiograms. These sets are half a century old or more, so the faults are predictable: germanium transistors drift out of spec, electrolytic capacitors dry out, band-switch contacts oxidise, dial cords stretch or snap, and rubber parts and belts harden. We replace failed components with compatible modern ones, clean and adjust the mechanics and check sensitivity across the bands — the original appearance and circuit stay intact.
An honest caveat: we deal with the electronics and mechanics of the receiver. We do not restore wooden cabinets, polish or repair the furniture side of radiograms — if the cabinet needs cosmetic work, we tell you straight away. The electrical side of a radiogram, including the built-in record player, we will bring back to working order: from recapping to valve sourcing.
Typical faults in valve and transistor receivers
On valve receivers the power supply suffers most: dried-out filter capacitors produce the characteristic 50 Hz hum, coupling capacitors start leaking DC and the sound distorts, valves lose emission and the output transformer can go open-circuit. Diagnosis proceeds stage by stage: we measure voltages against the schematic, trace the signal from the antenna input to the speaker and isolate the faulty assembly instead of swapping parts at random. Burnt-out dial lamps are replaced along the way — they make the radio look alive again.
Transistor sets have a different typical list: germanium transistor degradation in older models, a crackling worn volume control, oxidised switch contacts, the aftermath of leaked batteries — corroded contacts and board traces, snapped telescopic antennas and cracked ferrite rods. On modern digital receivers we repair tuning encoders, displays and USB charging circuits and replace batteries. After the repair we verify reception on every band, and all work carries a 3-month warranty.
