Yaqin Tube Valve Amplifiers

The previous schematic was a little tough to read. This one is much clearer thanks to Trevor Lowe.

A big thanks to one of the site’s readers, Steve Kulak, for donating these two schematics:

 I thought I’d make a Yaqin facebook group to see if it turned out to be a better place for discussion etc. Facebook allows uploading of images and a more casual interface than my website. Please join up and see how it works out. Ultimately it will only be any good if people use it.

Dear visitors, after a downtime of about five months, I’m glad to say the site is now back up. This was an unavoidable result of difficult personal circumstances. All I can say now is welcome back.

I was given a schematic for this so have added it.

I’ve got the schematic for this model and so have added a page for it.

Enjoy

I’ve added the excellent subscribe-to-comments wordpress plugin. I was finding it difficult to keep track of comments, and I hope this will help you guys and gals too. When you comment, simply make sure you choose to subscribe to the page and you will be notified by email when anyone else comments. The comments aren’t ‘threaded’, but they will hopefully be relevant enough for you to be glad of the notification. For those that are interested this site gets about fifty hits a day now which is quite sweet. I’m hoping to order a 100B soon and will publish anything of note when I do.

If anyone has an article or further information on Yaqin, please send it to me and I’ll be happy to add it to the site.

I’ve been trying to source a supplier in Hong Kong that will offer cheap shipping – preferably via sea mail to keep the price down. I’m hoping to make an order with a view to reselling but it would help if I could get some pre-orders (at least as a gentleman’s agreement). The more I buy in bulk the lower the price should get. There is also the consideration of customs duty when they arrive – this would have to be divided by the number of units and added to the final price. Approximate prices, minus customs duty and based on the current exchange rate and a bulk order of five same model units, are:

• MC-10L – £200
• 100B – £310
• 300B  – £400

If anyone is interested at this price (possibly less depending on the size of the order) please let me know. I wil be checking them for safe operating voltage when used within the UK.

UPDATE 03/10/08:

I’m afraid that personal circumstances have meant that I’ve put very little time into this venture recently. I’ve had some sporadic interest, but not enough to be able to commit to a larger purchase. The cost of shipping is so high and the worry of customs duty clearly (and understandably) puts people off. I will try harder though and who knows? – something might actually happen!

I appear to have been successful in starting a Yaqin audio page on Wikipedia. This is harder than it sounds as you have to meet various criteria, including a very frustrating and at times hard to substanciate assertion of notability not to mention the easy to stumble upon weasel words!

 Wikipedia is harder than you think!

See http://en.wikipedia.org/wiki/YaqinAudio and contribute sensibly where possible.
