There comes a time in the life of all tube amps when they must be serviced and re-tubed. Tubes wear out and should be replaced periodically, either partly (power tubes only) or fully, (pre-amp and power tubes). Its amazing the difference in the sound a properly re-tubed and serviced amp makes. (more on tube wear)

   TUBES. |
We import tubes all the time. They come matched and graded in sets of pairs or quads, We check them and match them again before installing them into amps because sometimes the matching done at the factory is not quite up to our standards. When we remove the old tubes we check these in our tube tester to check their grading. We then select new one's closest to that grading. This re-tubing technique ensures minimal bias adjustment and most importantly the amp sounds the same as before, or we select tubes and bias them according to the customer specific requirements. (See notes on biasing) We know the difference in sound between the tube brands and can advise on tube selection for tone.

Being a manufacturer meticulous about the quality of our 
tube amps and other great gear, Sherlock Amplifiers

is also available to our customers as part of our amp restoration service. We have a selection of Tolex from the USA for that purpose. We can also replace speaker grill cloths. Again we have a selection of grill cloths from the USA specifically for that purpose.

| 120v to 240v POWER TRANSFORMER CONVERSIONS. |
|---|
We offer a 120v to 240v power conversions service for our Australian customers importing American amps. This may be accomplished by rewiring the amps primary wires on the transformer if the amp has a universal power transformer. If not, then the 120v power transformer has to be replaced with a 240v equivalent. We also find in some cases a slight bias adjustment is required (on Tube amps).
Price for amps fitted with Universal transformers:
To re-wire 120v primaries to 240v on a universal power transformer, including power plug and fuse change, check over and bias tweak if required. $110
Price for amps not fitted with Universal transformers (Domestic):
Replacement power transformer for:
100w Amp $290-$350
50w Amp $250-$300
Labour for transformer replacement:
Includes voltage testing as is on a step down transformer before removal.
Checking for any other faults, including bad tubes etc.
Removal of the120v transformer.
Installation of new 240v transformer.
Other tasks required for 240v amp conversion include:
Change mains plug or supply 240v power lead.
Change fuse for 240v operation.
Check internal voltages as per the original 120v transformer.
Check and adjust tube bias if necessary.
Check general operation.
Final assembly and audio test.
Labour: $110-$165 Email for quote
| VINTAGE GUITAR AMPS |
|---|
There's nothing worse than inspecting a vintage amp only to find most of the old vintage parts have be replaced with their modern day counterparts. This of course destroys the value of the amp, not to mention the tone. We take the attitude that if it's worth repairing it is indeed worth repairing properly. We will repair it back to its original status. We have most vintage amp parts in stock If we haven't got the part, we will source it from overseas.
We will only use quality or original replacement parts, ensuring that the gear/equipment functions the way the manufacture intended or better, so that in the long run, you save time and money.
