Common questions

Before you drop off.

Do you work on valve/tube amplifiers?

Yes - valve biasing, valve replacement and output transformer fault-finding are routine for us. We work with both vintage and modern valve equipment.

Is a quote always free?

Free initial assessment on most small items. Larger gear (valve power amps, complex receivers) carries a small bench-time charge that's deducted from the final repair cost.

Can you recap an old amp?

Yes. We'll specify like-for-like or upgraded capacitors as appropriate and explain the trade-offs before any work starts.

No fix, no fee on most small items

Got something to fix? Tell us about it.

Free diagnostics on most small items. Honest quote, no upsell, no fee if we can't fix it.
