I wish manufacturers tending to the audiophile market will stop selling sexy packages with the cheapest caps they could find. An extra $20-30 to the price tag will not "break the bank" and the improvement in sound quality is well beyond swapping tubes!!!
Well, I am going to have to replace the coupling caps in a cheap Chinese amp I bought for grins, since I blew them up in less than a week

Wow, that's not an amp - it's an adventure...
Hopefully the leaky caps didn't take out the tubes and if so, then no big loss anyway. Go for the better quality foil/film caps. They are reasonably priced at these small values and are much superior to any metalized cap (Solen, Auricap, Clarity and the likes) you might find for a few pennies less.
Make sure the rated voltage is above the B+ if it's coupled into a resistive load, double that value into an inductive load.
Since I see a few tube amps in your inventory, why not peek inside them all. Once you re-cap one amp, I guaranty you would want to change them all...

Just got my 332 a few days ago. Still using the stock tubes, but ordered those military version M8100s. I have no idea how to tube roll, so I'll have to figure that one out.

With an Arcam 73 and RS-1, using a regular RCA cable, I get no hum or any other noise, but the sound is very dark and murky. Colorless in a word.

Definitely less harsh then using portable amps with this setup. Hopefully I don't end up breaking the M8100s or anything else when I try to roll them.

Congrats on your new amp fateicon! Good choice on the M8100's. You'll hear that it is quite a nice improvement from the stock tubes.
Tube rolling is easy. Just remove the protection caps, rug the tube gently from side to side, while pulling it out of its socket. If you wanna be careful, use gloves or something, so you don't leave any grease on the tubes.

What capacitors would you recommend as a replacement for Solen 30uf (36x53mm)?

Good suggestions, thanks. I bought some nice film caps from Parts Express right after the incident - just haven't had time to put them in yet.

Could you post a pic of the ceramic tube sockets in your amp perhaps? Is this a new addition to the current production DV332 amps?

Thanks
Hi Musicmind



Yeah, I shall post a few pics in a couple of hours or so of the large ceramic tube holders. Basically they are white and almost identical in appearance to the smaller tube sockets.

I think that they must be a new (and much welcome) addition to the current production DV332 amps.

Hey guys I've been lurking this thread and am planning on buying a DV332.

I'm planning on ordering from Jasmine_Chine on eBay, and I just received an email from him asking me if I wanted to buy it from him outside of eBay, if I do this I am not entitled to PayPal/eBay buyer protection. He has nothing but good feedback from people on Head-Fi, and I'm currently weighing the risk of me getting scammed.

Do any of you know what voltage North America power outlets use?(Canada)

How much would you save... by doing that? My guess is... not enough to lose the protection - though, I'm not really sure its worth anything anyway (based on my experiences with PayPal).

Don't know about Canada... but US is generally compatible with 110-120 volts. My guess is that Canada is similar.
post #1121 of 1888
I remember I was asked the same thing. I don't remember the amount I could save by paying outside, but it was not much, so I decided to do it the normal way through ebay. If something goes wrong in the process, I guess it's easier to get it sorted when done the "right" way...

Thanks very much for the pics AntiGeek.

I'm glad DV are fixing this little problem which was a nuisance in an otherwise great amp.

I have bought from Jasmine-Chine outside of EBay many times, no problems. You still use Paypal, so you have some protection especially if you use a credit card, but in my experience, it's not an issue. Jasmine is a 100% on the up and up seller.

Canada is 110/120V just like the US.
post #1124 of 1888
Yes, Jasmine is HIGHLY recommended from me. Fastest shipping and service I've encountered to date.

30uF is a large value - what's the application?
For values of 2.2uF or less I had good results with Hovland, but I'm sure other foil caps (i.e. non-metalized!) are decent too.
For a large value like this you might have to compromise due to space considerations. KimberKap have decent metalized caps that sound to me much better than Solen. Auricap is another option, but the price is much higher last time I checked. I also heard good comments about Clarity caps and i'll have a chance to audition these next week in a newly done crossover for big Usher speakers. Preliminary "report" is good.
Bypass the metalized cap with a small film cap around 10% the value. In your case, a 2.2uF is close enough. You can try it with the Solen or just order the better caps and do the job right.
When selecting caps, determine the actual operating voltage and pick a cap with a slightly higher voltage rating. Don't go with much higher voltage than needed, because that usually means thicker dielectric, which is bad for audio applications.
