I remember growing up reading Stereo Review and seeing all the positive reviews on the BW series speakers.
Thanks for the "teardown".--- begin sig file ---

Re: Bowers and Wilkins ZEPPELIN crappy caps
I dont even trust ipods, mine which was just out of warranty had copletely lost audio in the right channel, then a year later it randomly died, and made a clicking sound from the internal speaker a few times, then totally dead.
Over $150 for a small thing that fits in your hand that doesnt last more than a year of less than 3 hours use a day! .....

Re: Bowers and Wilkins ZEPPELIN crappy caps
I have to admit, these things sound great, the second one (later model) I open up which suppose to have been upgrade with better power supply, but I found bad caps (Su'scon) as well. Sorry for people that paid $500~600 for this thing.
They are sure hard to put the grills back on.Never stop learning

Re: Bowers and Wilkins ZEPPELIN crappy caps
It doesn't surprise me one bit, my Polk Audio powered subwoofer is full of CapXons, you'd think for the price they charge for these things they could use good caps, but I guess saving a few cents on the caps boosts the profit margin, and since most audio equipment isn't too hard on caps they can get away with it most of the time. In fact the only relatively recent piece of audio equipment I have that has good caps is my Kenwood VR6070 home heather receiver which is 100% Elna and Cornell Dubilier.

Re: Bowers and Wilkins ZEPPELIN crappy caps
Just brought one of these full of, suscon capacitors. They are not physically bloated but most are open circuit:
3 1500uf 16v all test fine
6 220uf 25v 4 open circuit the other 2 very high ESR and no capacitance
6 100uf 16v caps all open circuit
2 22uf 50v caps open circuit
1 100uf 35v cap 40 ohms with 20uf left
I changed all the caps and the primary’s for high end power supply caps, also added some more heat sinks with thermal glue to the floating TO220 power transistors and output diode....
I can see why these power supplies throw tantrums, the units run very hot I don’t think the passive air intake from the speaker movement is enough to cool the unit properly. Bad design for the price of the units new, luckily I only paid £10 for mine faulty and it’s in mint condition I’ll grab some photos before I put it back together.Last edited by ReeceyBurger123; 04-25-2021, 04:13 AM.Please Do Not PM My Page Asking For Help Badcaps Is The Place For Advise, Page Linked For Business Reasons Only.

Re: Bowers and Wilkins ZEPPELIN crappy caps
I feel like modern Samxon GK's are pretty decent. I usually replace a lot of Samxon when I see them if I have a better replacement but usually they test very good esr when removed.--------------------------------------------------------------
