As well as sending me a lingo (see here), John sent down a Klout amplifier... It had the same issues as this one, only was completely dead. A re-cap fixed it.
It was also fitted with the Keltik Bass extension module. This is simply a low pass filter to allow the amplifier to drive a woofer as part of an active cross-over system.
It's really nicely made, and was given a re-cap to ensure reliable service.
The Keltik module is mounted on a single metal spacer which bolts up to one of the four transistor heat spreader cap screws. Remove the spacer before attempting to remove the cap screw, or the whole thing locks up. The other end is supported in a groove on the speaker terminal output insulator.
There's a single connector to remove on the board.
We'll need to remove that screening can, which is simply desoldered.
Same the other side...
.. to gain access to those hidden electrolytics.
Look at all those precision poly caps... nice!
You'll need 2 off 220uF 16V , 8 off 22uF 50V, 2 off 2.2uF 50V and 1 off 10uF 63V .
They needed replacement, some were physically leaking, and smelt horrible during desoldering!
Another saved from landfill!
