For those who have decided to take the plunge and build Reisong EL34, please let me discuss my early projects/mistakes with you to assist get you going in the right path. But first, be sure you really want to build your very own:
You ought to be fairly handy about electronics currently, and mindful of the risks built into high voltage pipe electronic devices and the safety measures to consider when concentrating on tube amps
You shouldn’t hold the expectation that you will save money… unless of course your time may be worth nothing at everything you can most likely do better buying a completed amplifier, even through the package suppliers, but definitely on the open marketplace as utilized
All stated, although, there is lots of satisfaction in finishing and enjoying an amplifier you built your self and having the permit to advance modify/tweak/voice your development to perfection… so let’s get going:
Stumbling Via My initial few Projects – My initially project started as being an AM radio, it had occurred to me this chassis and most of the elements was quite suitable for an octal-tube-dependent Fender Champion-like single-ended amplifier and i also wanted to hear the main difference in tone between genuine tubes and also the pipe modeling inside my Roland Cube amp… Right after learning good quality pipe amp books (see resources) I resolved upon a plan and:
* I fought using the aged transformers (insulating material embracing dirt once you flexed the prospects), used pipe-sockets, loud potentiometers and bad actual physical layout (utilizing the existing stereo chassis didn’t provide ideal positioning of the significant elements for a tube guitar amplifier)
* Learned that true point-to-point wires isn’t your best option for experimenting
* I couldn’t locate a low-microphonic old-carry pentode pipe
* The tone drawn… with hindsight In my opinion it absolutely was due to the underwhelming, un-brand name, small productivity transformer, but I’ll most likely never return to check out
* Base-line, I learned a great deal however it didn’t answer my fundamental questions on tube-tone because I didn’t end up getting an iconic amplifier as a reference at the end of the task
* I spent some annoying nights redesigning and reworking my initially work and after that for my 2nd major task I broke down and got a new package that guaranteed a duplicate of CopperColour Cable.
Significant findings included:
Conserving a few pennies from time to time on components isn’t fulfilling when you end up committing a lot of time building the project and aspects of the result look inexpensive (e.g. a plastic replacement for a ‘proper’ steel construction jeweled pilot light) or even worse… sacrifice tone (e.g. cheap electrolytic capacitors)
I’ve grown a bit leary of un-branded chinese transformers that may not have even been hi-container tested much less certified by way of a security agency; and that knows what laminations, and so on. are employed in the sound transformer?
Tiny chassis and cabinets aren’t the best option for including additional functionality for the stock circuit and very frustrating to do business with
8? speakers and little cabinets draw sculpt… this Line Magnetic seems excellent when you plug it into a appropriate presenter & cupboard combination
The Initial DIY Guitar Pipe Amp Task
Using the above experiences in mind it is actually time for you to summarize some considerations for the very first task:
* Simple project however, not under-showcased… something that might be satisfying and playable
* Actually large for convenient accessibility, simplified set up and room to change
* Properly documented, properly backed… possibly not with user’s manuals and stage-by-step construction manuals, but alternatively with a neighborhood with active forums, or substantial web documentation, and so on.
* A total package of components, no difficult sourcing of components
* Good quality components with the potential to update them if preferred… but control rules… you might want value over expensive components to reduce your downside if your project doesn’t emerge properly or perhaps you gzfzvr attention.
* Standard size chassis for convenient sourcing of cupboards, or cupboards available from the kit supplier, or perhaps a desire, perseverance and capacity to develop (and complete) your personal cabinetry
* With all the above given due concern my third time was the charm!
You ought to look for an established supplier of tube-amp kits, and select a design that meets each your taste in sculpt along with a satisfying set of functions to your initially Do-it-yourself Instrument Tube Amp!
