Report KG Balanced Dynahi build discussion thread in Do It Yourself Posted June 20, 2020 On 6/5/2020 at 10:03 AM, Applewood said: Finally completed the dynahi. I really enjoyed this DIY processing. Based on previous experience, this time I spent more time on selecting parts and adjustment, also increased heat sink size, quiescent current increased to 75mA. The gain keeps the original design value (200K/10K) and there is no background noise even using high efficiency earphones. Thank you everyone for your experience and information on this thread. Is the second pic showing a transparent cover on the amp?
