I'm super in for a pair of the 19" plus whatever kind of kit you offer Colin. Looks great!

Would you say that using a linear regulator enables your unit to be more true to the original 1073 units as say a DC-DC converter version does?Slenderchap said:canidoit said:Is your method better than the DC-DC converter method in regards to these units?

I cannot envisage a single reason why you would use a DC-DC converter (except perhaps unless you owned a factory that makes DC-DC converters).
In no particular order;
They are all different package styles so you would need to choose a brand and stick with it which can be a sourcing problem if the supplier is out of stock.
They are comparitively large.
They generate noise which is not good for a high gain system.
They introduce noise spikes onto the supply line unless you have a very low impedance supply output.
They are generally unreliable.... compared to a linear regulator
.... and of course most importantly..... expensive.... a linear regulator is only a few pence.

Have you compared other 1073 - 500 series clones that are using a DC-DC converter and an original 1073, and compared it to your 500 series clone, and have you noticed any sonic differences?

matta said:I love the layout, I noticed some of the smaller details as well, the holes around the 2N3055 heatsink for ventilation, preventing the heat potentially damaging the PCB in years to come. It also looks like there is onboard regulation as well if you decided to use it?

south2577 said:I'm interested in 120 of the 1U modules ;D...... but a pair will do for starters.
Keen to know the price? Kits partial or full?
Some of us aussie's could share postage?
Nice work Colin.
Sarcastic Sound said:what size case did you design the 1u pcb to fit into?
Collin how about if its like grayhill switches that are soldered on the PCB board and the grayhills fastened to the faceplate?Slenderchap said:You should not attempt to have a circuit board where the pots are fastened to the faceplate and the connectors are attached to the rear panel..... apart from the fact that the mechanical tolerances are not good enough you will eventually find the unit fails as the solder joints fracture due to the expansion/contraction of the chassis over the years....
