Bedini Amplifiers - two different builds/layouts of the same model amp?

I agree, they're 40+ years old at this point so most need some touching up. The photo above was repaired before I owned it. I've had a few in for service with a reliable repair technician and most are going strong. Usually just a few small things need replaced and they're back to working order. I'm mostly after the rarer ones, and less interested in the main stream models. They had many unique variants of and one-offs which sort of adds to the allure of the brand and those are the ones I'm interested. So far all of the ones I've listened to have been worth the trouble of getting them repaired. The main one I am after now is a Bedini/Strelioff 200 which was their first amp. As of now I've got a 10/10 (only a few given to dealers), a 25 DE, these one MEGS in this thread and a couple other odd ones. One is a 200/200 S/N 001 that i think might be a prototype model?

The mass-produced MkII models and BA-8xx models I am less interested in.

Shahinian Loudspeakers are still around (at least via email) and I talked to them a few years ago and to this day they still keep a Bedini amp at their factory. Most of their speakers have low impedance loads so that maybe something to do with them pairing them together.

@hoten03 ,Too many to remember. I understand your interest with collecting these, however I would caution you with buying these up. Although nice amps, many out there have had, or are, in need of some service....ime. The photo of the open chassis shows this......2 of the Motorola output transistors have been replaced ( shiny ones ). What does all of this mean ? Find a good tech who can do measurements / upgrades / repairs. Just as an fyi. The speaker designer Richard Shahinian ( RIP, 2017 ), recommended the Bedini amplifiers almost exclusively with his offerings. My favorite was the MEG 25/25 ( if I am remembering the model correctly ). My best, MrD.

Thanks for the response @mrdecibel . Do you know if the MEG just mean upgraded power supply? Or transistors? I've also got a 25/25 that I suspect is a MEG but does not have it written anywhere on it. From other 25/25s I have seen it seems to be a bit larger.

Which Bedini amps did you own? I've in the process of putting together a collection of them.

Here's the 25/25 in question. Once again thanks for the input:

Your 1st photo is of the later production MEG 100 / 100. Owned a MEG 100 / 100, similar to your 1st photo ( and owned so many other Bedini models ). The models / dates are shown on the circuit boards. The Meg model had an excellent bottom end, in both tonality and rhythm. Enjoy! MrD. 

The 2nd was is broken at the moment so I haven't been able to do a comparison until it gets fixed. The first one sounds great on my B&W speakers

So how do they sound relative to each other?

That's really interesting. I hope an informed member has the answer.
