Tube Gear
Restore first. Modify with a reason.
Diagnosis, maintenance, restoration and justified modification of tube and selected vintage audio equipment—from guitar amplifiers and hi-fi to studio electronics.
Fix the real problem first.
Diagnosis
Find the actual electrical or mechanical fault before replacing parts by habit or folklore.
Maintenance
Safety, contacts, tubes, bias, noise and reliability.
Restoration
Preserve the useful circuit and historical intent while making the unit dependable.
Modification
Change the circuit only when the modification has a defined technical or musical purpose.
Studio preparation
Tube microphones, preamps, compressors, guitar amplifiers, hi-fi and field-coil loudspeaker systems are treated as working systems—not display pieces.
