That is a transitional amp. It is the only one I have seen with the line out and turret boards. The line out is usually an indicator of a PC board amp, and this amp certainly was built at the end of the turret board period.

We should start it's own thread and remove it from the DR v. HJ thread.


Sounds like a great plan. What size should I make the photos so they fit? I'll see if I can borrow the good camera from my wife.

Can you move the posts to a new thread, or shall I start a new thread?

Hopefully Old School Dave will chime in with pic size guidelines. I usually have to take mine down to 25%, but I am sure it depends on the camera and settings.

I think if you start a new thread, I can move the posts to it but I don't know for sure, I'll just have to try it.

FWIW - I usually size images at 640x480 or 800x600... for large gut shots I'll just post the url vs. reducing it.

I started a new thread under "1980 Hylight DR103".

I also just posted the urls for the photos.

Perfect! If possible, knock down the resolution to 96dpi. That setting still looks good on HD monitors but helps keep file size down.

It's an inspection thing. You examine each solder connection and mark it if it looks good. This makes it easy to see if you missed one.

Out of curiosity, do we know much about these other subcontractors?

not much.

Glynn please correct me if I am wrong.

We know there were issues between HIWATT and Harry Joyce Electronics regarding production capability and monthly quotas.

DR needed more than HJE could (or wanted to) build in a month. DR had to do what he had to do.

At one point DR hired one of Joyce's top guys and had him building amps at the Kingston facility. Harry was angry to see this, but he was limiting production. Reeves needed amps!

HJ Electronics was the largest contractor, wiring chassis from mid 1970 continuously through the end of Hylight electronics and the end of biacrown, but from time to time DR had to find shops to supplement the production from HJE and in house Hylight builds.

I see... It would be nice to know who they were because I feel they deserve their share of credit in the Hiwatt legacy also.. I've never seen any less than 100% quality inside an original Hylight :mrgreen:

Hmm.
I don't really agree.
Even Harry Joyce, was just a wire jockey performing well spelled out wiring requirements. HJ and his crew were master technicians, but they did not design or have any voice in the the design of HIWATTs.

In my opinion HJ has been given far more credit than he was ever due.

Don't get me wrong Clayton! :mrgreen: I would never question the design or build mastery of DR! In fact, I agree with what you are saying about HJ too.. The 'in-house' build quality was the pinnacle IMHO (not suprizing given DR was on site) and as far as I am able to generalize with Hylight builds, the quality of work of these mystery contractors was also top notch.. Not just HJ in other words.. Great technicians as you point out but not a patch on DR!

Maybe a stupid question. Had beed assambler and tester been the same person? My Custom 50 is from 1977 and QC is from DR:

DR checked it out, but it was wired up by HJ electronics.
Nice Amp!

Any chance someone can repost the original images? They seem to have gone broken. Thanks!
