The amp/preamp belong to HFV member Nishant. Nishant has provided this beautiful cab to him. I will ask Srikant to post pics once he complete it.

Thanks Shailesh for your detailed review. This is a killer amp/preamp combo.
I actually requested Aniket to design a hi quality amp which should be easy to build and economical. He has done an excellent job on this combo. The Power amp can be configured into 75W or 120W per channel. It has onboard power supply and protection circuit. The user only has to connect a transformer, minimum soldering requires as it comes as fully soldered board, including PCB mounted heatsinks. The Preamp is very good too and can be use as headphone amp as well.
Here are few builds and reviews on Lencoheaven https://www.lencoheaven.net/forum/index.php?topic=30648.0

I am posting few pics of PCBs and modules

Hi Sachin, where to get these modules. Please share

Thanks

Found an old Cassette player sheet metal box in the electronic store which i found I could DIY as a compact setup for my DD amp and pre. Here it is. Front is not full aluminum but a Alubond sheet cut to size. Used the transformer original wires iteself without any wire extensions. Have tried to separate the power section from the sensitive input signal side. So far no hum and works like a charm. Have some holes drilled for venting... need to see if this is adequate.
