About 30 years ago, the owner had bought a good working Tremolux combo and this "non-runner" came with it as a spares donor. It had been in his loft ever since and now it's time for a total electronics rebuild.
 |
| A little bit scruffy. |
 |
| Pity we're not going to re-do the tolex as well as the internals. |
 |
| The chassis is looking a bit tired. |
 |
| The filter caps are in various stages of decay and the cover is missing. |
 |
| A few valves missing, but we're going to replace them all anyway. |
 |
| This is where most of the work is going to happen. |
 |
| And a view from the other side. |
 |
| Check-out the hand wiring. |
 |
| The mains transformer turned out to be defective, so we'll have to find a replacement. |
 |
| This is looking a bit better now. |
 |
| Some new filter capacitors fitted, those carbon resistors are still good and can stay. |
 |
| The original amp was 110v ac input, a bit of new labelling applied at the rear end. |
 |
| The new mains transformer courtesy of Mike at Danbury Electronics. The size is perfect, it drops straight in. |
 |
| A close-up of some new pots. |
 |
| This is the replacement for the peculiar 350k/70k tapped pots used in the treble positions. I can supply these if anyone needs them. |
 |
| When fired up, it turned out that the output tubes were running a bit hot. This is a little mod for adjustable bias, now we can trim it a bit more accurately. Apart from this little bias issue, the amp worked first time. |
 |
| Topside after completion. Those tube shields cleaned up nicely. |
 |
| A cleaned up front panel with a matching set of the original design knobs. |
 |
| The finished amp. |
 |
| IEC fitted at the rear, instead of the grubby old Powercon that was on there. |
