My wreck conversion/clone.

[JamesHealey]

Here is a 1973 Carlsbro 60TC converted into a wreck.

Blasphemy I know, but I got the amp for £100 and I needed a wreck in my life.

The layout is different due to the chassis but i've used Polyester Orange Drops, Carbon Film resistors, F&T Filter caps, Silvered Mica caps.

Only differences from Francesca are as follows:

Transformers & B+ Chain:

Carlsbro Transformers (considering a Toneslut OT)
Zener Diodes to drop B+ to 410v
Carlsbro Bias circuit to produce -37v


Circuit:

68k Grid leak rather than 150k
1n Ceramic and 1n Polyester to make 2n coupling cap as seen on others
150pF PI Fizz cap
47k Feedback resistor


but she's a beauty, sounds fantastic extremely stable all the way up to 10 on every dial, and i've managed to get the noise down to a very acceptable level.

cool conversion. You might want to replace the CC screens for longevity, Try seeing how hot the get before you play the amp at a gig or somewhere else where failure might mean disaster

You can see the changes here..

cheers for the heads up, i'll put in some 7W Ceramic Wirewound they should be suitable?

Sure, I use the square 5 w ceramics all the time.

5W or 7W metal oxide or wirewound will be fine.

as the boys said...yup
