I can't seem to find the lamp and LDR part numbers in the Harbinger PDF in Europe, so I need similar parts that work. I found this Univibe kit from Banzai in Germany: http://www.banzaimusic.com/Univibe-Upgrade-Kit.html It is quite expensive though at 10 euros plus 8 euros shipping costs. It also doesn't include part numbers or specs, but I trust Banzai as a supplier and I can also buy lots of other stuff there.
Locally, in the Netherlands, I usually buy from Newtone. They have this lamp for sale: http://www.newtone-online.nl/catalog/product_info.php?products_id=1465 In the text it says that it can be used for "Madbean Vibrato". I assume that's the Quadrovibe project. Can that lamp also be used in the Harbinger project, or are the specs different? It seems that it is smaller, but is that actually a bad thing for this project? Other tips for finding the 'right' lamp for the project in Europe are welcome.
Then there's the LDRs. Newtone carries several: http://www.newtone-online.nl/catalog/index.php?cPath=47_80 There are two that can be used for the Easyvibe, according to the project. The difference is in the range of the light/dark resistance, 10k/50k to 5M (type9200) or the bigger 5k/20k to 20M (type9203). So, is bigger range better or should I go for 5M dark resistance? The 9203 is also used in the Quadrovibe.
How is the sound difference between the Quadrovibe and Harbinger anyway? Has anyone tried both?
Last question: how is the lamp life in this project? Could I solder it down and not have to worry about it for the next ten to twenty years with moderate use (let's say about four hours a week generally) or is it wise to socket it in some way?
EDIT: I built it with the Banzai kit and it works perfectly! Please scroll down...
