Help with my Hiwatt

I have had this DR105 for a couple of years now and I love it. I know a little about Hiwatt eras and models from looking up info online but a couple of things I'm stumped on. The green and white sticker on the chassis says it was made in 76. Nov. 9 I believe it is. It is a two hole input model but a...

DR105 bias question

I have a DR105. I did an easily reversible bias pot mod that uses a 1 Meg linear pot in between the 47K resistor and the ground. Before the mod, i was getting 60 mA for the bias setting. The pot brought it down to 42. The plate voltage is 498 V. I should be getting around 35 or so, i believe. Is hav...

Re: '76 DR105 problem

the tubes seems fine. no redplating. the resistor value was faded pretty bad. the amp has two 4 amp fuses in it. a slow blow in the mains and a fast blow in the HT. i will change the HT to a 3 amp. i changed the 470 ohm and the 100 ohm resistors, too. i dont have a cab here at the house, so i will n...

'76 DR105 problem

on my 1976 DR105, my 470 Ohm 10W resistor keeps unsoldering itself and coming loose. it is the original green one. the 100 ohm 5W one seems to be ok (original green one, too). i have resoldered these resistors at their junction a few times and after about 15 minutes of loud jamming, it comes loose. ...

Re: Wanted DR103 in the US

Dave's DR105 is a nice, clean amp and very tempting to buy, just the head case is pretty beat up. i want one with a pretty good shape h...
