Krell Restoration


Want to restore my FPB-200. Works fine, but must repair my 802s and thought I should have the Krell caps checked out and replaced as needed. It's been 15 years of hard use. Should I send it to Krell, or use a local, highly regarded specialist located near me on the West Coast? Got the Krell carton, but shipping could be deadly. Any experience with third party repair?

Hi Dderham1948 - I just saw your post. Just a few additional comments.

When you say "its been 15 years of hard use" it tells a lot.

Whether it goes back to Krell direct or not, may be dependent on the weight / distance / logistics. There is a crossover point when weight and distance can rule out sending to the manufacturer. In my case almost 200 lbs. I had no choice. A few friends and I are lucky as there is a certified past Krell tech in the Ontario L5B XXX postal code. This person has even worked on the $150K Krell Master Reference Amplifier. So when using local techs credentials are very important.

BTW - I could not confirm from your post.
When you say 802s do you mean two (plural) B&W matrix series or other series of B&W 802's ?

The FPB series has real synergy with the 800 series matrix line. My generation krell 600 was chosen due to the synergy with my reference matrix 800 speakers. The same ones used by Dan D'Agostino when his main system was FPB series with matrix 800. He liked the 800 series matrix line so much that he designed his own Krell built to B&W spec Bass Alignment Filters.

I just got off the phone with Dan recently and he gave me some more tweaks for my system if I ever get tired of listening to music. :^)
Very open and easy to talk with. I encourage you to call him at 480-575-3069 in Arizona. He may know someone qualified in your own backyard if sending the amp back to Patrick at Krell becomes a no go.

Cheers and Good Luck.
Hi ct0517, can you share some of the tweak's Dan D Agostino shared with you, I have talked to him myself on the phone over the last few month's, do tell please.
Yes, a FPB-200 with a pair of Matrix 802s S3.

Live is Nor Calif., know of no one Krell certified here.
Any experience with the KRC-3? also 15 years of hard use. Should I have the caps replaced on it?

Ct0517. Front of Matrix woofer is partially separated from the speaker. May only need to be glued, don't know yet.
Anyone know of a hidden stash of Matrix drivers? Willing to pay.

Is FedEx Freight different and safer than the FedEx that ruined Jsd52756's KSA-200 (above)?

Dderham1948 - this site lists parts and prices.

B&W Parts and Pricing

You can type in your model and series and it lets you know the availability of parts and their prices. They are showing out of stock on your woofers.
This is not a problem. Your woofer can be brought to any reputable speaker rehab shop in your area and repaired as new.

Loosen the bolts on the woofer slowly. When all are starting to move (not seized) cradle the bottom of the woofer and start taking the bolts out. The woofer will want to fall out from bottom toward you so cradle it. Once bolts are out the woofer may be stuck to the cabinet if its never been out. Slowly pry away with a pick. When it gives it will be all at once so keep cradling it. I put two small pieces of green painters tape on cabinet just above the woofer showing which wires blue / brown go where. For when you put it back. Bring woofer to the shop. They will repair it and inspect the spider for flabbiness. If it need replacing do all woofers same time. You will be back in business.

Your Krell preamp is not like the Amp. It doesn't go through the stress cycles of high heat/ cool down. I would have it inspected at same time. Its not a given that all capacitors wear out over XX years on a preamp. i.e. My Studer tape failed. My tech thought for sure it needed new power supply capacitors. When checked they were at new condition specs still. (knock on wood :^) .
It turned out to be another problem. let us know how u make out.

Cheers
Hi Dderham1948, your Krell Krc-3 does not need to be recaped as often as the class A amp's, you may be able to get 5 to 7 more year's out of the krc-3, however, it would cost alot less money than any krell amp to get recaped, smaller and alot fewer cap's is alot cheaper to do, I know a KAv-300I is about $600.00 to $700.00 to fully recap, so your pre-amp should be the same price or likly cheaper to recap, I believe it's worth doing if you enjoy the sound of the krc-3, after the 500 hrs of burn-in of a NEW recaped Kav-3, you will be impressed, it will sound better than new, cheers.
