  • Re: Beovision Avant amplifier + speakers

    Finally managed to get a clear sound from a project like this... Was given the amplifiers and speakers from an old avant With the help of beobuddy diagram i got a suitable transformer from an online store here in europe and a power supply pcb from eBay. If it's not against forum rules i'll post the links to where i bought them. https://youtu.be/6dL2h1SfU8c Any comments on circuit are appreciated.

    Already downloaded the schematics for the 3400 and the service manual for the 2000. Nevertheless I could really use the service manual update for the 3400 as it perhaps has a parts list and circuitboard diagrams, which I find really handy. Going to dig into the amp. starting with the power supply The triac is toast. It is a 2N6342A so I need to find a replacement. The thing is, that without the parts list don't know if it's the original one or if someone has already replaced it. Cheers

  • Beomaster 3400 Barn Find, worth restoring?

    Hi all, At a house clearance I came across a BM3400 in somewhat good cosmetic condition so I brought it home . Opened it up and this was the scenario Haven't turned it on as there are some loose connections on the transformer and there are bulbs missing and the tuning dial assembly is falling apart Is it worth restoring? I can live without the tuning dial as I rarely listen to the radio, only records or CD Does anyone have the service manual that can send me by PM? Cheers, Duarte

    Hi, It's been a while... A job and a house change took all the time from me... I'll try to remember how I got around the other problems with my BG 2.Tone Arm not lowering or raising in the right position; 3.Sometimes the cam wheel didn't engage; 4.Replace RCA plug for a DIN Plug As for the tone arm, I thought it would suffice to do as ther service manual says and adjust the two screws in the bottom of the turntable. No luck there. I don't know what the previous owner(s) did but the

    Hi again! Having understood how the turntables worked, I could proceed to setup the working one (Type 5243). Issues to be addressed: Slow motor; Tone Arm not lowering or raising in the right position; Sometimes the cam wheel didn't engage; Replace RCA plug for a DIN Plug Starting with the motor. It was running slow.I mean, really slow. As I had another motor and, like a kid who wants to play with it's new presents, I decided to swap the motors, cross my fingers and hope that the speed on

    Continuing... I spent the next few days with both Beograms opened to understand the differences and how the turntables worked. When you press the button, the motor starts and the tonearm moves to the start of the record , 17,25 or 30 cm diameter, according to what you choose in the speed selector (more on how that works later on) That movement of the tone arm and it's return to the resting position is governed mainly by the cam wheel, which you can see in the following two pictures (Source http

    Hi, First of all Hello BeoWorld. I've been in love with B&O products since ever, I loved browsing the interwebs and window shopping local B&O Store, ever wondering when one of those works of art would be sitting along with me in the living room, filling my eyes and ears with joy. Then I found more about the vintage B&O, in my opinion more visually appealing than the new products and would't break the bank owning one. A win win situation. From all the B&O, history two items
