I also saw this type of cheap turntable in my country. There are splitted in two categories:
A) The cheapest and the worst stereo systems which includes radio, usb, aux and a phono with toxic plastic chasis and mechanics and of course a ceramic cartridge. The entire mechanics of plastics if is...
Hello guys! I remembered recently about a Romanian magazine since 1994 where was presented an interesting phono preamplifier based on FET transistors. As previously most listeners preffered to buy or construct either "Le Pacific" or "Boozhound" preamplifier, I decided to come in help for them...
Hello guys!! Long time ago I decided o try the schematics of the Le Pacific preamplifier.
If I try to power the entire bloc from a DC source the hum is higher, so I power it from 3 x 9V battery but they don't last so much. I also placed a 220uF/50V capacitor between + and - for reducing a...
Hello!
After an upgrade at a netbook from a HDD WD 500GB to a Crucial SSD 256GB I want to find an utility to the old HDD in the case of backup or recover data.
My question is : if that WD HDD is on sata 3, which rack should I buy with USB 2.0 or with USB 3.0? My notebook has 2xUSB 2.0 and...
Well, all I can say at the moment is that I am living on a block of flats, at the last floor, and near me, in my room I can receive at a half of level the WiFi signal from my neighbour. My OS used is Windows 8.1 with license (not hacked) and the driver for the WiFi module of my Acer is shown on...
My notebook is at a distance of 10m from the router. There are other devices that are using th WiFi router in my family such as: another 2 notebooks and 5 smartphones.
Hello!
I bought this year from the french hypermarket Auchan a pair of WiFi headphones, brand Rapoo, at a very good price quality ratio. All it's ok when listening to the headphones (clear sound, distance of 10m) but I have an issue with them: when using the WiFi of my notebook - Acer ASPIRE V5...
Hello! Some days ago I recovered an FM block from a mini-system but I don't know how to connect those pins. The block is from Mitsumi FE415-G11 like this. The main board of the mini-system was broken down and I can't identify where those pins are connected. From 8 pins I found:
-where the...
Thank you! I reduced the number of turnes from 9 to 4,25. I tried to tune into stations.. I received some of them but the sound is not so clear as it's written in the book. Also if you want to tune into stations, after selecting one station it is desired to re tune even the input circuit...
GT311 is not a problem. The same diagram was also posted on a romanian book and the author recommended the BF200 or 214. But also the diagram was designed for OIRT spectrum 65-73MHz. How many turns should I cut?
Hi everyone! I found on a book and also on the internet this interesting diagram of a FM direct conversion radio.
The problem is that it was designed for the FM OIRT, not CCIR. As a direct conversion the oscillator works at half of the frequency tunned as is described. Will I be able to adjust...
However the problem was solved long time ago by me,even if I didn't have at that time the manual. The ball (last picture) made all the friction. I used a mechanics spray and the problem was solved. Now I bought the manual to have the electronic diagram of the phono in case when something will...
