Glasshouse C-core TVC Passive Pre-amplifier

Glasshouse C-core TVC Passive Pre-amplifier

Glasshouse are proud to launch the all new C-Core TVC Passive Preamplifier. Centre to the design are the Glasshouse fabulous C-core auto type volume control transformers taking TVCs to the next level.

The chassis, measuring 235mm (wide) x 320mm (depth, with knobs fitted) x 130mm (height) is made of black powder coat 2mm aluminium, the front panel is 10mm thick aluminium alloy black anodised with 2 x 40mm diameter black anodised knobs at the front controlling the selector and volume. The chassis is vent free offering a dust free environment, important for all switch operation.

An important feature we have developed for this kit is the switch clamps, these can accommodate any of the switches we currently stock. The effectively can hold the switch firmly in place anywhere within the chassis in perfect line with the control knobs. Thus you can position the switches to allow for incredibly short wire lengths from the signal inputs to the selector switch and from the transformers to the volume switch. The shafts of the switches is linked to the front by using couplers and extension rods. We all know that voltage signals do not drive long lengths of wire well - this is a great solution to this.

We are offering standard single ended transformers that use RCA sockets for their input and outputs . For the balanced source and amplifier user we have the balanced transformers, these wire up to XLRs.
The chassis is large enough to allow for 6 off RCA input pairs, 2 off RCA output pairs and 1 off RCA record pairs, together with 4 off XLR input pairs, 2 off XLR output pairs and 1 off XLR record pairs. The idea being you use the blanking plugs/caps to cover up the holes you are not utilising.

As a result of there being so many different options on this kit, we are selling the chassis and fixings as one product for £195.00 + vat. You then have the option of which transformers to buy, which connectors, which switches and which wire you would like to use in a recommended shopping list. 

We can build this kit up for people at a cost of £200.00 + vat.
