Help anyone just got a hk 730. Recap is done. Never had sound when bought. As soon as i plug in the amp board it blows fueses and the rear side of the amp board humm threw speakers. Added shunt lugs to pre amp. Worked for 2 mins then blew fuses. If amp board isnt plugged in. Doeant blow fuses also white ceramic resistor smokes. Also moved and replaced power transistors with rs model. I saw that the 4 transistors on the heat sink were 2 different models nec

Fantastic! I picked one up at Goodwill for under $50 and plan on doing a recap soon. Looking forward to seeing what it sounds like after the recap.
My 430 is powering a pair of original Klipsch Cornwalls and I could not be any happier with the sound at this point.
I personally love the looks of the receiver and think it looks great at night with the radio and needle lit up.

I've been looking at other reviews of this receiver and found most are glowing which is what prompted me to write this after my recent auction site purchase of one. Its design is relatively austere, keeping to the same 330C looks without function lights. Not a big deal but wondered why HK chose to eliminate them and keep all the dial lamps lit with the phono or aux section on. I liked the previous 630/930 lighting setup more which made sense. The lack of pre/main jumpers isn't a dealbreaker but another reason I suppose to go for the 730 instead of the 330/430. Now here is the subjective part; most of the reviews I read on the audio sites claimed a superior sounding 430. I don't find that the case in my example. I find a rather low-powered but average appealing sound suitable for a small office or bedroom capable of driving bookshelf speakers adequately. I didn't find the tuner especially adept at finding and holding stereo broadcasts well and found my tuning meter to be flakey. The phono section is just OK, nothing more, I just don't see what the big deal is about this amp, the controls of lo cut are almost imperceptible, the contour is overdone. The knobs have very slight detent markers which are impossible to see, having to use your sense of touch to feel the marker etching to find the position. I always end up going back to my Marantz 2245 over the HKs and I've had the 330B, 630 and 930 twin power. I do find the HK 430 appealing in its design so I'm guessing this the main attraction. In all honesty, the NAD 20 watt per channel 7120 outperforms this HK 430 for its price and size, I don't think it can be beat for its sound either, just looks like you need to hide it. Just my 2c. of course, realize that my not so excited opinion is also based on the prices these amps fetch on the big auction site.
