The ones I saw had 1446's in them and then they went to HG's and then for a while they had some that had fets in them. I almost bought one. I assumed I would have to finish it as in it was a Heathkit someone else put together that was almost right. At the time I did not want to mess around so I...

Well if the enclosure and board looks like it came from ICA no amount of paint will make it look like anything it is not! That is not a slight against ICA either! If your just building a warmed over version or what all the other builders are also building with the same designs and components...

Price too high and I hate that user interface. I want knobs and switches and a meter thanks!

I run a lot of hi end home aduio gear. If you start with the right components and the gear and room are setup properly 1 watt from a hi end amp amazes a lot of people. So 350 watts per channel into a nominal 4ohm load with an efficient loud speaker and plenty of headroom and bandwidth in the...

On the switching supply front everyone knows they are electronically noisy and they always have been. It is a matter of of if the noise is where you talk and listen that matters. You can reduce the noise some and move it around but you will never get it all out. I think the "Mega Watt" units...

I have a 35 year old 100 foot extension cord. It was used by the welders on a union contract and after the building was built they threw it away! It is still going strong and for the last 6-8 years has been powering my second fridge out in the garage.

Well I think everyone makes junk today. If they can get it made in China cheaply they will from component parts to boards to entire units. They all want purple squirrels to work for them as well! Just like all of the engineering firms and design firms in Detroit! They use less and less...

As I understand it the tuner is fantastic and could tune a trash can!

I just ordered a G90 from Radioddity and got it and all acc. bundled for $472 and that was with taxes and free shipping!

Most amateur radio's have a pretty wide audio bandwidth a D104 would effectively degrade that. Is that on purpose? Plus the Icom has +8V on the cord you could either power the unit or you could replace the mic element with and electret and power it from the radio.

You would be much better off all of you guys with a decent signal bipolar transistor amp or duel transistor amp. Even if they are HG's! That is not worth the money or the time. I had an amp on the back of a radio once. It was fine since I was driving a 1986 Toyota 4Runner and had no airbags...

That chasis can not dissipate that much heat! I would never push a radio that hard. I think that is a recipe for failure with non-rf mosfets! I know the parts are cheap but shipping and labor add up in a hurry.

For the record even my 1998 President Lincoln the manual squelch is touching beyond belief and the auto squelch should be called " Alligator Station" or "Super Bowl" switch because it will cut off all but the strongest stations. So from the sounds of it the latest greatest still has that fatal...

No issues with mine or the parts I have bought from him!

Well the voltage regulator on the control face does freq. fail. So it is no wonder most would start there. How hot is your room that it is hot enough to shut this amp off? How come this problem seems to be unique to yours? Any links to more info on this from other sources would be great! I have...

You said old! I do not deal with old tuning transformers that had mica cap built in but as I understand it they can get mold growing on them??? I might be misunder standing this. I have seen green poly caps grow something white that splits them open.

Mica all the way! The use of ceramic caps unless we are talking a doorknob is normally about cost. You would see CB amps loaded with ceramics because they are cheap! That is even more true today. Voltage tolerance surge tolerance, rf resistance and heat resistances favors mica. Few of us can...

So I got a GREAT deal on 10 NOS Jan 4x150A tubes. So I would like to build an amp from scratch but I need a design I can copy. I can build almost anything if I have a solid design. I can not on the other hand sit down and design my own amp! I have repaired many different amps including tube...
