I have a dead Stagg BA60 guitar amp that I'm wanting to convert into a simple 50w or more powered speaker as cheaply as possible consisting of a line level input and volume pot.
The dead amp cab has a 12" speaker of around 5.5 ohms and unknown power rating (was supposed to be a 60w amp), and a working 240v toroidal transformer that I've tested to be putting out 27-0-27 volts AC and would like to use that as my power source.
Not being very experienced in this sort of thing can I assume that a cheap Chinese TDA7294 amp board with the following specifications would work with my transformer?

Product Specifications:
Output power: 100W (maximum distortion power)
Operating voltage: 28V +0 +28 V (AC)
Product Size: 90mm X 90mm
Amplifier board for the mono
Product Features:
PCB board with 2.0mm thick FR4 double-sided design.
Preamplifier using KA5532.
After stage amplifier using the U.S. National TDA7294 inside the power tube uses a MOS transistor, so the sound a little taste of Tube Amplifier.
Protection circuit uses a dedicated the UPC1237 chip, delay protection, the midpoint offset protection, overload protection.

Apart from the crappy Chinese blabla lingo in the ad, those modules can work quite well.
I have a Chinese TDA7297 module for a few dollars/Euros and use it to power two high efficiency monitor speakers for rehearsals.
There's lots of info on chip amps in general on this forum.Chip Amps - diyAudio
