Oh dear, that is horrible!
I remember seeing those ILP modules advertised in 'Practical Electronics' when I was a kid.

Re: MT20 Cutting out even with 16ohm speaker

What power supply are you using with it? The original supply?

Power valve degrade faster than preamp valves, preamp valves will typically last 3 or 4 times longer than power valves.
I'd say good preamp valves last even longer than that. Years and years if you are lucky.

Re: Are genuine bias pots available OR120

Just bought 2 x bias pots and 2 x hum pots. Turns out the seller lives about a mile away from me! Lots of other interesting stuff for sale too.

Re: New Product Announcement 9/28/18

Hmm, I really want one as it would go well with my superlight Barefaced cab.

I like how it sounds in this demo:

Re: Can anyone help with Schematics(for my tech)?

Gee electronics are guitar amp specialists in Warrington and have a good reputation from what I can see:

(I have no connection to these guys, just googled it.)

Re: Orange Rocker 30 Problem.

Or the other thing to do is to measure the AC voltage at the spade connectors where the thick yellow wires attach - TX4 & TX6.
If there is no voltage here with the amp switched on then the 6.3V tap is toast and it is new power transformer time.

Re: Orange Rocker 30 Problem.

Doh ! You have already done this!
If these test good, then check the voltage to ground (using AC setting on meter) on either side of the fs3 and fs4 fuseholders.

I have a Rocker 30 schematic, fuzzy but useable, can send it to you if you like.

Cheers,
Jon

Re: Orange Rocker 30 Problem.

It's not about the EL34s getting their 400 volts(plate voltage), it is about them (and the other non-glowing preamp tubes) getting their 6.3V heater supply. The Rocker 30 is a weird setup. It uses a mains transformer originally designed to supply a valve rectifier (5V heater) as well as preamp/power...
