Hi Drew and Søren,
Initially I really thought there was a difference, but I wasn’t sure.
The more I use my renovated Beomaster 4500 the better it sounds and I have less than an hour on it with 39 more hours to go.
My McIntosh 2255 didn’t have that big change, BUT McIntosh powers their amps at full throttle for a factory set period of hours, several days as I recall and they don’t do it for nothing.
And then there is my fabled Beomaster 4400, now IT had a break-in period, or more accurately a break-down/break-in period…. but that is another story entirely.
I wonder what my Beomaster 2400 will sound like after Benny changes everything as he plans. At least now I know in advance what to expect.
Funny thing about that little amp, its last day “on duty” it played beautifully, I mean really well. Initially there was almost (I said almost) no difference between it and the 4500, although that distinction rapidly changed in the 4500’s favour.
In regard to the double-faced tape I first went to Home Depot® and all their tape was way too thick. I found the tape I did at Staples and really thought it would work, but not so. Just not sticky enough.
The previous owner used twit ties like for a garbage bag to hold the black plastic parts in place. I tossed them where they belong, not in the 4500, but the garbage.
Maybe it is OK the way it is, after all I make due with my BeoCenter 9000. I just have to be EXTRA careful not to disturb the glass panels.
Progress with antique electronics is never a straight line, but progress is being made.
That said the BM 4500 took so much time today that I didn’t have a chance to so much as look at my Seeburg jukebox let alone the S 45.2 speaker. One day at a time….

I heard back from Benny and this is what he said:
“I checked your BM 2400, you are right it is very clean. Two of the lights are out, but I will replace them all. The tone control pots are all working which is good, but needs rest of the usual stuff, power supply rectifier, certain capacitors, bias circuit pots.”
This doesn’t really explain how my BM 2400 had several near-death experiences and came back and I have no idea what a bias circuit pot is, but at least it is repairable, which I knew it would be, and repaired it will be.
Should be interesting to see how a rebuilt BM 2400 stacks up to the BM 4500.

Hi Dom,
Your precise answer went a bit over my head, but it explained to me, for the first time, why my Beomaster 2400 got so very, VERY HOT. The right channel went out and man were the heat fins ever HOT! (I think I made my point, the 2400 really over-heated.)
In any case, it all came back and never over-heated again….. and next week will be on Benny’s bench.
Thank you for this helpful explanation, which is much appreciated.
Piaf: “I checked your BM 2400, you are right it is very clean. Two of the lights are out, but I will replace them all. The tone control pots are all working which is good, but needs rest of the usual stuff, power supply rectifier, certain capacitors, bias circuit pots.”
Good news. Glad I was wrong.
Hi Rich,
It is not a question of right or wrong, the most likely scenario would have been for my experience to be like yours…. only it wasn’t.
You see Peter, I DO have good luck, on occasion. I would add, overdue, but welcome.
I am very pleased to have learned from Don why my 2400 got to terribly hot and recovered and went back to normal.
So is this repair assessment what everyone expected, or slightly better due to the good pots?
Just wondering, cause I gonna have it fixed regardless because I really like this 2400.
