Happy New Year to all, and a massive thanks to my many customers.
Thank you for trusting Old School Guitar Amps with your gear, and for supporting a new, local small business.
We have big plans for 2026, and are already getting busy, with just a few spots still available for January.
Send us a message, or email, or give me a call if you have a valve guitar amp that needs some love.
Rock on,
Scott 🤘

Who let the smoke out?

R6 let the smoke out… but only after someone replaced the 1 Amp HT fuse with a 4 Amp fuse 🤦🏼‍♂️.

Always use the correct fuse Groovers!

For those playing at home, it’s a Marshall JCM2000 DSL100 from 2011. Fortunately it has the “Issue 20” PCB so doesn’t suffer from conductivity on the board.

This one came in for a faulty power switch, but needed a bit more than that…. new output tubes, new bias trim pots, two new bias-sense resistors and the correct 1A HT fuse as well.

Got a valve amp that needs some love? Old School Guitar Amps in Kingsley can help!

On the bench today… Fender Prosonic.

Extremely versatile and very well-made amp only produced from the mid-90’s to early noughties.
Designed by Bruce Zinky and originally released as a Fender Custom Shop offering, these are not your typical modern Fender amp.

Jason’s 2x10 60W combo came in for a new speaker plug and a once-over. I was impressed by how many different tones are available… from spanking Fender cleans to face-melting high-gain, and also by the excellent quality of construction.
If you see one of these for sale, buy it… they’re awesome!

It’s been a busy 6 weeks since the launch of Old School Guitar Amps. Thanks HEAPS to the many customers who’ve trusted us with their pride & joy.

From vintage early 70’s Fenders, to nineties & noughties Marshalls and the ever-present Fender Hot Rod Deluxe/Devilles, we’ve had plenty to do.

Here’s a few pics and details of one of the amps we’ve had on the bench lately…

Jon’s Fender Blues Deluxe Reissue had an intermittent, ugly distortion happening on both channels. It had been to a couple of techs over the years, and been completely retubed, but the problem persisted… intermittently.

We discovered the problem was induced by vibration… it didn’t happen at low volumes, and it didn’t happen at any volume when the back panel was fitted…. which made the cause REALLY difficult to find.

After a LOT of troubleshooting, we identified one of the two channel-switching relays was the culprit. Even though channel switching was working fine, vibration was causing the relay’s contacts to oscillate open/closed, making the amp sound terrible.

We fitted a couple of new relays, and the amp was as good as new… better even, because while we were in there we fixed a bunch of other known issues common to the Blues & Hot Rod series Fender amps: Things like low-voltage power supply resistors mounted too close to the PCB and causing heat-damage; brittle solder joints at ribbon-connectors, plate-load resistors that are under-rated for the voltages they see, and poor-quality filter capacitors that are known to fail.

If you’ve got a Fender Hot Rod or Blues Deluxe or Deville that needs some love, Old School Guitar Amps can help.

Drop us a line via Messenger or email and we’ll be in touch ASAP, we promise!

Waxed Boards?
Great if you’re surfing, not so great if you’re a vintage Fender amp owner.

Around 1974, Fender started dunking some of their completed guitar amp circuit boards in molten wax. Apparently, the idea was to keep moisture out.
50+years later, often the wax hasn’t held up too well and has absorbed moisture and other gunk. This can cause the circuit board to become conductive… allowing DC voltage to flow to where it shouldn’t be.
The result? A wide range of symptoms, including unstable bias, and intermittent crackling or random static noises that come and go.

Got a vintage Fender that’s not sounding its best? Drop us a line, and find out what we can do to help.
Old School Guitar Amps… for real, old-school service.

A recent ‘Old School’ creation up for sale…

Search FB Marketplace for “Tweed Champ” because the link below seems broken 🤷

G’day Groovers,
Anyone else find it difficult to get tubes for their guitar amp(s) in Perth?
I’ve been surprised lately by how many of our local guitar/amp shops don’t stock any tubes, or have a very limited range.
What’s your go-to shop in the metro area if you need tubes? And what’s their selection like?
🤘
