"fiih-300" - Holton based 300W power amp


Once again a powerful 300W Holton based power amp using the upgraded 200W modules. These have the more powerful dual die power FETs installed to allow the modules to produce 300W into 8 ohms and 500 into 4. 80,000uf of 100V filter caps all snubbed and an RFI/EMI power filter.

An over size heatsink is used but still runs up to over 50C. Tranni is 500VAC but will be more than enough to drive the hardest loads to high volume. Once more excellent Holton bass depth and control. Clear, transparent mids. Allover an excellent sounding amp.
