I've been using this brilliant piece of software for years but I think there's a missing function that could be useful to many diyers. I'm referring to hybrid bridges. Now I'm working at a little 2A3 amplifier and the idea is to use two silicon carbide diodes to ground and a 5Z3 on the positive leg. This solution has several practical advantages and works great. Would it be possible to add it? Many thanks.

Hi Fabio,

This is on the "to do" list, there have been a number of requests for this type of hybrid bridge rectifier where users want a vacuum tube top half and solid state bottom half. Spookily, I've been working on the simulator for this only this morning and have got some code working where the diodes can be different. Last iteration of the feature list is at ->?/g/duncanampspsud/message/67

As a general note and update for everyone, I've had a book delivered on Friday written by the "clever people" which has been been very helpful in getting the concepts for the core simulator to a level of accuracy and flexibility that will allow these kind of variations (Jiri Vlach / Kishore Singhal; Computer Methods for Circuit Analysis and Design).

The home-brewed first generation simulator in PSUD1 and PSUD2 is problematic to say the least. The second generation one (a variant on the first) I put together for PSUD3 over the summer is much more accurate, but wasn't scalable in terms of performance.?Additionally, it struggles to support some of the requested features like the hybrid bridge and the PSU splitting, hence me going on a book buying spree to come up with something that will fit the next iteration of the software.

Right... back to my circuit simulations... :)

Duncan
