In this category we list all the modules of the first post-war series, which  was manufactured very elaborately using tube technology. The modules were made in normal, double and triple widths and were therefore called cassette sizes 1, 2 or 3. Cassette size 1 has the dimensions: 47 x 134 x 265mm and fits perfect in our vintagetools VT7x racks, which we build in mono and stereo versions and sell empty or loaded with modules (if we have any in stock). Those modules are: V71, V72, V72a, V72b, V74, V74a, V74s, V77, V78. Double width modules are: TAB V76, TAB U73, V530 and V73. The V81 has triple cassette width. The double and triple width modules won´t fit in the VT7x rack, but we offer custom racking solution for those. Either a beautiful wooden lunchbox or a unique 19" rack can be build after the customers request.

There was no official name for this series of tube modules. It is therefore often called V72 technology today, since the V72 was the first and best-known cassette in this series. On our website we call this series V7X. Suitable racks from vintagetools are called VT7X racks. 

If you are searching for tube modules which are currently not available, please send us an inquiry. We have several customers who sell V72, V77, etc. and can broker modules.

The VT7x rack is the ideal housing for your tube modules.
