Re: Hulp bij 544 transformatie tweeter

Hi Rob, it's strongly advisable to use MKP or MKT 100 V capacitors in this passive crossover section of the MFB544.

Re: 544 beveiliging

Lucas. in de 544 zit bij de oudere uitvoering een beveiliging voor zowel de laag als de mid hoog. Later is deze er bij de laag uitgesaneerd en alleen de mid hoog zit er dan nog in. Was bij die van mij ook zo. Maar op de printplaat was de ruimte er nog wel, dus zelf maar weer ingebouwd. Zo heb ik du...

Re: MFB544 modification from /00 to /50 questions

Is er echt zoveel verschil tussen de drivers van de /00 en de /50 serie? Yes, there are...and some other intersting little corrections through the evolution of the MFB544 project in electronics. I've also excluded the tone control present below /50 revision that in some way cause sound to be a litt...

Re: MFB544 modification from /00 to /50 questions

Hi Salvador, thanks for your reply and i wish a happy 2019!! :D Sure, i've changed also these components, according to service bulletin regarding ad0163 introduction on 544. I also have let c566 on the Mid section with a 3,3 uF (same value as c568). Could this be the reason? In an approximately anal...

Re: Ortofon 2m Series fits perfectly AF977 shell dimensions

Sure but i think that an Ortofon 2m of high series (bronze, black,) will be widely better than GP412/422. I also own a GP412-II with an elliptical aftermarket stylus (thakker) and is quite equivalent to the 2m RED. But the main fact is the chance to upgrade this great TT with contemporary quality ca...

Ortofon 2m Series fits perfectly AF977 shell dimensions

Good news for AF977 owners, or with other Philips turntables, mounting the GP4xx series cart in a fixed holes shell. Vital dimensions of the Ortofon 2M series is exactly the same of the Philips GP4xx series. Verified with specifications and measuring. In my AF977 now sit a beatiful Ortofon 2M red. T...

Re: AF-977 bottom cover realign

Good Job!!! This new wood bottom cover is even more solid of the original, giving some extra mass to absorb vibrations.
Great idea to share with us. Perhaps, when you have time and the desire, you can paint the border of the same gray/black of the case.
Regards, Paolo

Re: AF-977 bottom cover realign

Problem fixed!! "hairstripper" :D has worked very well. With a little help of my hand :D protected by a glove, i could remodel the bottom and make touch the four rubber feet.

Re: AF-977 bottom cover realign

My paintstripper has also two fan speeds only. Summarized: My export market must be Italy ...... instead of Dutch Marktplaats. :P The Phase Locked Loop on the turntables is more a gimmick. All the DC motor-tacho electronic turntables from Philips up from model 22GA212 (1972) have about the same spe...

Re: AF-977 bottom cover realign

cut cut ... In Holland a malfunction Philips TT from 1970-1983 can be bought up from Eur. 10. For re-working and replacing parts for Eur. 40 you can sell it for Eur. 70-100...cut cut. I pay for this AF977 170 euros, and is the cheapest (because to restore) that i can found in Italy. I know that in ...

Obviously, when i try it it was leveled by spacers... My "hot air gun" have two temperature, the lowest at 300°C and the highest at 600. My fear is that the plastic has temperature shrinking properties, that led to uncorreptable condition...but if you have resolved, i think that is not this case. An...
