Loftin White based 45 SET amplifier

Insulating Copper Capacitors with heat shrink

Many of you will be familiar with the process of insulating your copper capacitors to remove any potential risk of shorting. Using large heat-shrink makes this process much easier. Simply cut a piece 10% longer than the capacitor, this will allow the ends to roll over the end of the cap neatly, as in the image.

Heat-Shrink can also be used to insulate stepped attenuators and selector...

We have been busy over the past few months working on a MKII version of our TVC pre-amp. We have sourced new transformers that initial listening tests lead us to believe are even better than the originals, and all the internal wiring will be the ever-popular Jupiter copper in cotton sleeving. For those people who have an old version (with a stepped attenuator) is is possible to upgrade to TVC'...
