2 ohm is VERY common with 'highs' amps. It's common to use two 4 ohm speakers per channel. You can even buy 2 ohm coaxials/triaxials to get full power from a single speaker.

For subs, few amps are only rated to go down to 2 ohms. Most go to 1 ohm and that's how people run them. Many run lower than safe (1/2 ohm).

Modern amps have muting circuits and should be virtually completely noise free on startup.

The amp's power rating/output has very little to do with the noise level.

The photos he posted were of a 2 channel amp that used two transistors per phase (high-side/low-side) per channel. I've never seen an amp that would mix a TIP33 and a TIP35 for a single phase. Mismatching parallel transistors is going to decrease reliability.
Anyone who purchased the repair tutorial, email me (babin_perry@yahoo.com) if you want to download the latest version.

Hi i will take pics of the output bjts before powering it on. In the meantime i have ordered pairs of tip35c and its complement
They should fit in and be compatible with the design. I hope
